Think you will find that Clichy is French! Justin Hoyte is the other English player. However MU + Chelsea have only got English players cos they can afford to buy and pay the best players produced by other clubs - hardly any come through their youth teams.
Apart from one season 15 years ago when United were lucky enough to have 5-6 youngsters appear at once, by my reckoning they have had one player come through to consistently play (Wes Brown) since, the rest they have bought (Rooney £26m, Ferdinand £30m, Carrick, £18m, Hargreaves £18m etc). I am sure Arsene would have loved to be able to afford them!
Try Scholes, Giggs, Gary Neville (injured), Brown, O'Shea, Fletcher, Evans, Simpson, Welbeck ..... and the players Fergie has bought, that you mentioned above, are British.
So for a club that we are constantly told nurtures English talent, the sum total in the 15 years since 1993 that Ferguson has brought on is Brown, Evans, Simpson + Wellbeck - hardly the backbone of the team!
BTW - Extremely proud not bitter, on a fraction of the money MU, Chelski, Scouse moaners, Spurs etc have spent Arsene brought us within a whisker when everyone said we will be mid table - imagine where we would be if he had the money Ferguson has spent!
