Arsenal legend Patrick Vieira believes his old club could face losing star duo Cesc Fabregas and Robin van Persie. He believes unless silverware is won quickly, key men Fabregas and Van Persie will leave in search of trophies.
Manchester City midfielder Vieira said: "These days I follow Arsenal as a supporter in England.
"I love watching them play and the Arsenal players are doing the right things but you have to add something to that - notably in physical impact.
"In my day Adams, Keown, Winterburn or Parlour might have had less quality but they would put their heads where others wouldn't put their feet."
Vieira hopes to play some part in City's FA Cup semi-final against Manchester United today.
And he added: "Arsenal don't yet have United's killer mentality. They often need three or four goals to win a match.
"The problem is the important players like Fabregas and Van Persie will end up asking themselves questions."
