Mikael Silvestre feels playing with the Arsenal youngsters has helped him feel young again. "In playing terms, they are replicas of each other as they put the onus on going forward but after that, they have two different principles," said the 31 year old, who could start against his former employers in Wednesday's Champions League semi-final at Old Trafford.
"At United, the squad is built in little stages but always around their pillars, (Paul) Scholes, (Ryan) Giggs and (Gary) Neville. They are the club's identity, their points of reference on the pitch and in the changing room.
"At Arsenal, it functions more by generations. There has been that of (Patrick) Vieira, (Robert) Pires, (Thierry) Henry. Now it is that of (Cesc) Fabregas, (Theo) Walcott, (Alex) Song, (Aaron) Ramsey.
"We give responsibility to these youngsters very early and we let them grow together. At Arsenal, youth isn't just an excuse.
"In the changing room, it is simple - to my left is (Jack) Wilshire, who is 16, and to my right is Ramsey, who is 18. We talk about things like the latest video games. It's good - I feel young again."
