Michael Mancienne has highlighted his work with Stuart Pearce as a crucial factor in his shock England call-up for this week's friendly against Germany.
Chelsea defender Mancienne has not played under Luiz Felipe Scolari and has been loaned to Wolves after two seasons at QPR - but Pearce has made him central to his recent England Under-21 plans.
"I've found working with Stuart Pearce very good, he's understanding and easy to talk to - he always gives an honest opinion,'' Mancienne said. "If he sees something not right, he'll talk to me and correct me. We've been wanting to do well for the manager.''
Pearce has also been credited with easing Theo Walcott into the national team after blooding him with the Under-21s - and Mancienne feels the Arsenal teenager is setting an example to other hopefuls.
"Theo getting in was a real morale boost, seeing youngsters getting drafted in to the senior squad,'' he said. "He's got the world at his feet. He can go on and do massive things because he has frightening pace, agility, and everything else. It was always good playing with Theo because he brings a lot of the team.
"You've seen his confidence go through the roof since his hat-trick (against Croatia). That is what he needed and now he'll go on.''
Mancienne was on the bench for Scolari earlier in the season but he feels his football development has come from his time on loan.
"It is good to be involved at such a massive club (Chelsea),'' he added. "I haven't really been there for two years because of loans but it was good to be back.
"I grew as a footballer when I was on loan and developed an understanding of the game. I've been in relegation battles and my experiences have improved me.''
England captain John Terry has given his backing to Mancienne's inclusion.
Terry said: "Fair play to Michael. We have got a lot of players at Chelsea and he has been eager to go out and prove that he is good enough. Myself and Lamps (Frank Lampard) spoke to Stuart Pearce and he said Michael has been his best player in the Under-21s.
"He will gain from the experience and his form has been fantastic for Wolves. They have had three or four wins since he has been there and he has got a bright future ahead of him.
"I don't want to put too much pressure on the lad but we all realise he is one for the future. He could come back and be in the Chelsea side, quite possibly. He has been eager to break into the squad. It is very unfortunate for all the young players at Chelsea that we have got such a big squad.
"In the Carling Cup, when the manager leaves out the likes of myself and Lamps, there are players who are not playing week in and week out who deserve to play.
"They get paid a lot of money to be part of our squad and it is difficult sometimes to throw the younger lads in but he will get his chance, I am sure.
"I went on loan to Nottingham Forest and it is a good experience. You go out and you have to stand on your own two feet. I heard Mick McCarthy say he turned up there on his own, he is living on his own and getting on with his football and that is all that the boy wants to do.
"He wants to play football regularly and, if he can do that at Wolves and other big clubs, he has got the chance to come back and maybe do that at Chelsea.''
Wolves manager Mick McCarthy hailed Mancienne: "Under the natural progression Michael has played regularly for the under-21s, so this is the next step. The England coaches must watch him every game and must like what they see - and I think he is ready.''
