UK’s Worst Performing Teams

Premier League Teams With the Lowest Win Rate Over the Last 10 Years

1. Norwich City

Average win percentage 2014/15–2023/24: 16.67%

Norwich City comes out as the Premier League team with the lowest win rate percentage on average from the 2014/15 to the 2023/24 seasons. They’ve been in the Premier League just three times during that period, accruing a win rate percentage of just 16.67%. 

However, this is a team that once finished third in the Premier League during the 1992/93 season and then featured in the UEFA Cup the following year, beating Bayern Munich before being knocked out in the third round. So, perhaps The Canaries’ time will come again.

2. Sunderland A.F.C.

Average win percentage 2014/15–2023/24: 19.30%

We head to the Stadium of Light next, where Sunderland has the second-lowest Premier League win rate from 2014/15 to 2023/24. They played in three of those seasons, during which they managed an average win rate of just 19.30%. 

The last time The Black Cats had anything to be cheery about was in 2014, when they made it all the way to the final of the League Cup, though they lost to Manchester City.

3. Sheffield United

Average win percentage 2014/15–2023/24: 21.05%

Sheffield United has the third-lowest average win rate over the last 10 Premier League seasons. They appeared in three of these seasons with an average win rate of 21.05%. 

They were most recently relegated in the 2023/24 season, finishing with just 16 points, the third-lowest points tally in Premier League history. They also broke the record for most goals conceded in a single season, totalling 104.

Premier League Teams With the Highest Loss Rate Over the Last 10 Years

1. Norwich City

Average Premier League loss percentage 2014/15–2023/24: 65.79%

Having the lowest win rate doesn’t always mean you have a high loss rate, as games can be drawn. That isn’t the case with Norwich. During their three seasons in the Premier League from 2014/15 to 2023/24, Norwich managed a loss rate of 65.79%, losing nearly two-thirds of all their games played.

2. Sheffield United

Average Premier League loss percentage 2014/15–2023/24: 60.53%

In second place, Sheffield United managed a 60.53% loss rate during the three seasons they were in the Premier League from 2014/15 to 2023/24, losing more than three-fifths of their games. They lost 28 of their games during the 2023/24 season, giving them a loss rate of 73% for just one season alone.

3. Watford

Average Premier League loss percentage 2014/15–2023/24: 52.19%

In third place, we have Watford, who have featured in six of the last 10 Premier League seasons, during which they managed a loss rate of 52.19%. They did reach the FA Cup final in 2019, but they lost 6-0, equalling the worst FA Cup final defeat in history.

The Most Reliable Premier League Teams To Support

As we all know, sports teams experience highs and lows. Sometimes, it’s best to support a team where you know what you’re getting, so to speak, old and reliable.

For this section, we’ve calculated the difference in win rate as a percentage for each Premier League team that featured in both the 2014/15 season and the 2023/24 season. This highlights the teams that have performed pretty similarly over the last 10 seasons. This doesn’t necessarily show the most successful teams to support, just the ones where you mostly know what you’re getting.

1. Crystal Palace

Win rate change 2014/15–2023/24: 0%

Crystal Palace is the Premier League team with the smallest win rate change from 2014/15 to 2023/24, making them the most reliable team to support. Crystal Palace have been involved in the 10 Premier League seasons, so for their win rate of 34.21% to be the same in the most recent season as it was 10 years ago, is perhaps impressive.

2. Tottenham Hotspur

Win rate change 2014/15–2023/24: 5.26%

Tottenham fans will probably feel that supporting their club can be a bit of a rollercoaster, as they’ve had a lot of lows and highs over the last 10 years. They were runners-up in the 2019 Champions League, losing in the final to Liverpool, and then they were humiliated 6-1 by Newcastle United, conceding five goals in just over 20 minutes.

But from the 2014/15 to 2023/24 season, there has only been a 5.26% change in their win rate, making them one of the most reliable teams in the Premier League.

3. Manchester United

Win rate change 2014/15–2023/24: -10%

As of 2014/15, Manchester United had only two seasons left before Sir Alex Ferguson, the greatest Premier League manager of all time, left. During such a huge time of change, which you could argue the club is still reeling from, for them to have just a 10% change in their win rate from 2014/15 to 2023/24 is rather miraculous.

County Cricket Teams With the Lowest Win Rate Over the Last 10 Years

1. Northamptonshire

Average win percentage 2014–2023: 9.52%

Northamptonshire had the lowest win rate in the cricket County Championship from the 2014 to 2023 seasons, averaging just 9.52%. During this time, they’ve been in the County Championship’s top division three times. Their highest finish in this time was in 2022, finishing sixth; in the other two seasons, they finished bottom of the table.

2. Worcestershire

Average win percentage 2014–2023: 14.72%

Worcestershire had the second-lowest win rate percentage from 2014 to 2023 in the cricket County Championship Division One, with 14.72%. In the four seasons, Worcestershire was in Division One, they finished bottom of the table twice and second to bottom the other two seasons. 

3. Nottinghamshire

Average win percentage 2014–2023: 21.36%

In third place, we have Nottinghamshire, with a 21.36% win rate percentage in the cricket County Championships top division. Nottinghamshire was in Division One for eight of the 10 seasons; they only finished in the top five twice during that time and finished dead last the same number of times.

County Cricket Teams With the Highest Loss Rate Over the Last 10 Years

1. Northamptonshire

Average loss percentage 2014–2023: 55.95%

The team with the lowest win rate over the last 10 seasons also has the highest loss rate percentage. Northamptonshire managed a 55.95% loss rate from 2014 to 2023 in Division One of the Cricket County Championship. Since they also had one of the lowest win rates in the last 10 seasons, Northamptonshire is truly one of the worst-performing county cricket teams over the decade.

2. Worcestershire

Average loss percentage 2014–2023: 55.75%

In second place is Worcestershire’s county cricket club, which had an average loss rate of 55.75% between the 2014 and 2023 Division One seasons. And as they had one of the lowest win rates, it's plain to see that performances often aren’t the best for Worcestershire’s supporters.

3. Kent

Average loss percentage 2014–2023: 44.25%

Rounding out the top three Cricket County Championships Division One teams with the worst loss rates is Kent, which averaged a loss rate of 44.25% from 2014 to 2023. Kent was involved for five of the 10 seasons in this timeframe, never finishing higher than fourth, and also finished bottom in the 2021 season.

The Most Reliable County Cricket Teams To Support

Lancashire, Warwickshire, Somerset and Middlesex

Win rate difference 2014–2023: 14%

There’s a four-way tie for the most reliable Cricket County Championship team in Division One. Lancashire, Warwickshire, Somerset and Middlesex all have seen a 14% change to their win rate from the 2014 to 2023 seasons.

Lancashire has the fourth-highest number of championships, nine, though their last one was won in 2011. But Middlesex has the highest number of titles of the four teams, 13, two of which were shared, one in 1949 with Yorkshire and the other in 1977 with Kent. Middlesex, along with Warwickshire, are the only two of these four to win a title in the last 10 seasons.

Somerset, on the other hand, hasn’t won a single championship in their history, though they were runners-up in 2016, 2018 and 2019.

Rugby Union Teams With the Lowest Win Rates Over the Last 10 Years

1. London Irish

3. Gloucester Rugby

Average win percentage 2014/15–2023/24: 41.24%

Rounding out the top three is Gloucester Rugby, who managed a 41.24% win rate during the 10 seasons in the Rugby Union Premiership between 2014/15 to 2023/24.

It hasn’t all been bad for Gloucester Rugby fans, though. One of the club’s biggest achievements in the past decade was winning the European Rugby Challenge Cup in 2015. They defeated Edinburgh Rugby 19-13 in the final.

Rugby Union Teams With the Highest Loss Rates Over the Last 10 Years

The Most Reliable Rugby Union Teams To Support

Win rate change 2014/15–2023/24: -4%

Saracens have the most reliable win rate in the Rugby Union Premiership, with a 4% change from 2014/15 to 2023/24, the smallest in the league. The club has won the Premiership six times, most recently during the 2022/23 season and has been European champions three times. They previously shared Vicarage Road with Premier League football team Watford.

2. Northampton Saints

Win rate change 2014/15–2023/24: -8%

In second place, we have the Northampton Saints, with the second-smallest change in win rate percentage. Between the 2014/15 and 2023/24 seasons, they had just an 8% change in win percentage, the second-smallest change, proving them to be one of the more reliable teams in the league.

They are also the current reigning champions of the Premiership, having won the title during the 23/24 season.

3. Harlequins

Win rate change 2014/15–2023/24: 10%
