January 2006 was a productive transfer window for Manchester United in addition to signing Vidic they singed French full back Patrice Evra.
Evra's fee was for a reported £5.5 million meaning that Manchester United signing half a world class defence for £12.5 million.
Evra has gone on to play over 350 times for the Red Devils in all competitions. The only trophy he has missed out on is an FA Cup. Given Manchester United's defeat to Swansea this season and the expiry of his contract at the end of the season its probable Evra will never rectify this.
