The Premier League season has already provided plenty of twists and turns.
But 11 games into the season, which team has the oldest line-up? Which team gives youngsters the most opportunities? Who is the oldest and youngest players in the top flight?
Press Association Sport has taken a look at some of the interesting facts and figures contained in the appearance data so far.
Tottenham have the youngest average starting line-up so far, at 24 years and 293 days. The Spurs team which beat Manchester City 4-1 in September is the youngest single starting line-up, with the team's average age 24 years and 40 days.
West Brom have the oldest average starting line-up - 28 years and 61 days. Tony Pulis' line-up for the second game of the season against Watford was the single oldest starting line-up so far with an average age of 29 years and 362 days.
Kelvin Davis is the oldest player to appear in the Premier League this season - he was 39 years and 17 days old when he played for Southampton against Leicester on October 17.
The oldest outfield player is Bournemouth's Sylvain Distin, who was 37 years 319 days old when he played at the weekend against Southampton.
The youngest player to appear was Reece Oxford for West Ham, who was 16 years and 236 days old when he started in their opening-day victory over Arsenal. No other player under the age of 18 has featured this season.
FEWEST/MOST PLAYERS USED:
Swansea have used the fewest players so far - 19, and have the smallest number of different starters too - 15.
West Ham have used the most players - 25 in all but have only used 19 different starters. Crystal Palace have given out more starts than any other team - 21.
CHANGES TO THE LINE-UP:
Liverpool hold the season's longest run of unchanged starting line-ups - four matches. Three teams - Chelsea, Manchester United and Sunderland - have yet to stick with the same starting XI in consecutive matches.
Norwich and Swansea have four ever-presents each - John Ruddy, Robbie Brady, Russell Martin and Sebastien Bassong for the Canaries and Ashley Williams, Federico Fernandez, Lukasz Fabianski and Neil Taylor for the Swans. Martin's appearance streak will definitely end this weekend after he was sent off at Manchester City.
Only four teams - Chelsea, Crystal Palace, Manchester City and Southampton - do not have an ever-present in their squad. While Jose Fonte and Graziano Pelle have started every match for Southampton, they have both been substituted. The same goes for Chelsea's Cesar Azpilicueta, City's Fernandinho, plus Yohan Cabaye and Jason Puncheon of Palace.
There have been six players - all goalkeepers - who have spent every minute of the season on the substitutes' bench: Mark Bunn, Adam Bogdan, Vito Mannone, Kristoffer Nordfeldt, Joel Robles and Declan Rudd.
However there are three outfield players who have been unused for 10 of their clubs' 11 matches so far. Kyle Bartley has sat continuously on the Swansea bench apart from a six-minute cameo against Manchester United and Spurs' summer signing Kieran Trippier has likewise been limited to just 10 minutes against Bournemouth. After starting Arsenal's first match of the season, Mathieu Debuchy has spent every successive Premier League outing among the unused substitutes.
Watford have fielded players of 18 different nationalities this season - the most in the Premier League - while fellow promoted side Norwich have named the fewest with eight. In total, players of 53 different nationalities have set foot on a top flight pitch this season.
