Barry, Milner and Wilshere all took the opportunity to defend the reputation of the maligned Three Lions manager following Tuesday's entertaining friendly against Ghana
The former Real Madrid boss has come in for criticism since reinstating John Terry as the permanent skipper of the national team, with Rio Ferdinand widely reported to have been ignored during the process.
Capello has also been derided after explaining that he needed to know only "100 words" of English to get his tactical points across, with some mocking his grasp of the language as a result, but Barry dismissed the doubters.
"The communication between the manager and players has always been good, has always been there," Barry told reporters.
"You can read things that are pretty negative but the important thing is the manager is getting his points across on the pitch.
"Any little negative seems to be getting blown up.
"But I'm sure the manager knows that comes as part of being England manager."
Wilshere added: "Before the World Cup he couldn't do wrong, and since the World Cup everyone has been getting onto his back.
"I think we need to give him a break. He is a great manager.
"He has proved it at clubs before and he has got a great record for England as well.
"He is one of the best managers I've ever worked with.
"People need to get off his back a little bit."
Milner was asked whether the criticism directed at the Italian was unfair and replied: "I think so. We just get on with it and try not to take too much notice whether it’s positives or negatives being said outside the camp, it's what's said in the camp [that is important].
"We aim for our goals and we know where we want to get to and we want to improve as a unit, as players and staff and it’s all about learning from past experiences from the World Cup."
Barry also admitted that the late goal conceded was a sign of inexperience, but said: "It's important we don't forget a lot of players haven't played together out there but you probably couldn't tell in that first half.
"In the end, [there was] probably a bit of inexperience conceding late on."
Concerning Andy Carroll's first goal for the senior national team, the stand-in skipper added: "That'll breed a lot of confidence into Andy.
"His overall performance was very strong.
"[He is] another great option for the manager."
