Patrice Evra
Surely one of the Premier League's most successful January signings since the winter window was introduced, Patrice Evra joined Manchester United in 2006 and was a mainstay of the defence until leaving for Juventus eight-and-a-half years later.
Alongside fellow stalwarts Rio Ferdinand and Nemanja Vidic, Evra made 379 appearances for United during his time at Old Trafford, 273 of which came in the Premier League.
Plentiful trophies followed, and his first three full seasons at the club yielded three consecutive Premier League titles before he went on to add two more to his tally in 2011 and 2013.
Indeed, not a season went by in which Evra failed to pick up at least one piece of silverware during his time in Manchester, with three League Cups, the 2008 Champions League, the FIFA Club World Cup and five Community Shields filling up his trophy cabinet.
Evra also helped United to the 2009 and 2011 Champions League finals and was included in the PFA Premier League Team of the Year on three occasions.
