But in a swipe at his former manager, Dixon says Wenger was in no way responsible for the Arsenal trainee's meteoric rise to stardom.
The former defender suggested that Wenger "is not a true coach", highlighting the example of former England star Cole, who progressed from a raw academy graduate to eventually become one of the game's very best.
'It had nothing to do with the coaching from Arsene'.
"But Mustafi? I spoke to Gary Neville who said Valencia couldn't give him away".
Next up for the FA Cup holders is a Europa League Round of 16 clash against AC Milan at the San Siro on Thursday.
'I didnt think the players that Wenger brought in are good enough.
"You don't get to where he is if you're stupid". Six of the current starting XI aren't good enough.
"Bouldy does get to do some stuff in training, but not as much as he would like".
'Arsene went through a period of allowing him to do a little bit more. Then it all went away'.
