3. Thomas Vermaelen
Things just haven't gone his way. The Arsenal captain who was assured of a starting position till last season sees himself as a bench warmer now.
The fact that Arsenal have lost most of their games when the centre-back has started adds to the misery.
Arsene Wenger has stated that it is difficult for him to drop the Belgian, but the formidable partnership of Per Mertesacker and Laurent Koscielny is rock solid and is one of the best defence's in the Premier League this season.
Vermaelen has been linked with a move to Napoli. However, the centre-back wants to stay at The Emirates.
