We're currently working our way through all the data regarding the reported injuries in the English Premier League over the past five seasons (2009-10 through to 2013-14). We’ve recorded a host of injury data for every Premier League team that was in the Premier League for each of the past five seasons – between the 09/10 and 13/14 seasons (Arsenal, Aston Villa, Chelsea, Everton, Fulham, Liverpool, Manchester City, Manchester United, Tottenham Hotspur, Stoke and Sunderland).

Michael Essien comes in a close second with 13 months spent on the treatment table, thanks mostly to a long layoff in 2011 with a knee injury.
