4. Mikael Silvestre
After falling out of favour at Manchester United, Mikael Silvestre looked to keep his career going at a high level, and it was Arsenal who offered him the opportunity to stay at the glamourous side of the Premier League table. After making 250 Premier League appearances for United, it was assumed that the Frenchman would fit straight into the Arsenal XI, and in theory he should have, but after causing dressing room unrest with the likes of Emmanuel Adebayor and William Gallas, he was released in 2010 and he went on to Werder Bremen. The former France international still plays, as he is currently employed by MLS side Portland Timbers, though now at the age of 36, retirement isn’t far away.
