There is plenty of debate about which of the Premier League’s four biggest clubs is the greatest of all time.
But, with a few exceptions, it is difficult to find a team that is completely without merit.
There are plenty of other factors to consider, too, including the relative power of the top clubs and the relative strength of the two English top divisions.
For instance, Manchester United, who are a league-leading 8-1-0 at the top of the table, have won the title four times in a row, while Chelsea have won just once in 12 seasons.
But the English Premier League is still far from the top tier of football in terms of sheer quality.
A look at the best teams in the English Premiership over the last 20 years:This table, which is based on Premier League statistics, lists all the top 20 English teams over the period between 2003 and 2014.
The teams in bold are the top-three in the table at the time.
All are now either the top four or the top two, although there are exceptions.
The teams at the bottom of the list are the ones who have won two or fewer titles in a single season, and have not had a top-four finish since 2001.
This table lists the top 10 English clubs over the past 20 years.
The top five English clubs were all relegated from the Premier, as were all of the bottom six.
However, the top three clubs have all won a league title, while the bottom three clubs lost the Champions League and the FA Cup.
This chart, which shows the top ten Premier League teams over a period of 10 years, shows that the top teams have won 11 Premier League titles and six FA Cups in that time.
The top two clubs, Manchester City and Liverpool, have two Premier League trophies each.
There are some notable exceptions, though, including two of the four top-flight clubs who were relegated in the 1980s: Nottingham Forest and Portsmouth.
Nottingham were relegated as a result of their losing the European Cup Winners’ Cup in 1987, while Portsmouth were relegated because they failed to reach the FA Youth Cup semi-finals.
The latter incident saw them qualify for the 1984-85 campaign but finished just a point behind Manchester United.
Portsmouth, however, qualified for the final of the competition in 1988 and went on to win the trophy for the first time in their history.
They were relegated from their highest league position and finished the season with a 19-point advantage over the bottom two clubs.
This table shows the teams in which Manchester City have the most Premier League victories since 1997.
The club is currently second in the league in the title race, behind Chelsea, but their recent title defence has been overshadowed by a succession of recent injury crises.
The club has lost just one player since the start of this season, while their other main signing has been left-back Marcos Alonso.
This map, which highlights all Premier League matches played in the last 10 years and also shows the number of points scored and conceded, illustrates just how difficult it is to predict who will finish as a top four club over the course of a season.
The chart shows the average number of games that each team has won since the end of the 2013-14 season, with the team with the most victories at the end earning the title.
Manchester United’s winning streak in the Premier is only the third-longest in the history of the club, behind Leicester City and Tottenham Hotspur.
Chelsea have been the most successful at winning the title in the top flight in the past decade, with Chelsea winning 15 consecutive titles from 2004-09 to 2010-11.
Arsenal’s winning run has been at least as long, if not longer, than any other team in the modern era.
The Gunners have won their last 14 league titles and eight FA Cups.
Liverpool, who finished second in last season’s title race and have won four league titles in the same period, have the best record in the entire Premier League.
They have won seven league titles, three FA Cups and one Champions League trophy in the four years since they were relegated to the Premier.
Southampton have won only one Premier League title in 10 years.
Tottenham Hotspurs have won six titles in 12 years.
Chelsea have the highest winning percentage in the whole of the English top flight since the 2010-2011 season, although they have not won the league since 2011.
Arsenal have won more league titles than any club in the previous 30 years, although the club has been in the bottom half of the league every season since 2011-12.
Chelsea won the Champions Cup last season, but the team did not reach the final, leaving them with a 20-point gap to the bottom-two clubs.
This map shows all Premier Leagues matches played over the next 10 years in the format of total goals scored, conceded and goals conceded.
