5. Thomas Vermaelen (Arsenal)
Thomas Vermaelen seemed like the ideal candidate to captain Arsenal following Robin van Persie’s departure, but for some reason the burden of the armband has apparently brought out the worst in the Belgian defender. The 27-year-old’s poor form saw him dropped to the bench along with Szczesny for much of the second half of the season, and he is now being linked with moves away. Interest from the likes of Barcelona and Manchester United suggests he still has something to offer, but he hasn’t looked the same player this year and perhaps isn’t the battling leader everyone thought he was. Together, he and Szczesny have been at fault for a large chunk of goals conceded by Arsenal this season, which just isn’t good enough from two senior players.
