Robin van Persie has not acted up at Arsenal as he waits to join Manchester United. The Sunday Mirror says Arsenal insiders insist van ­Persie's attitude to pre-season training and preparation for the new campaign is faultless.

He does not appear to be a player making waves to force a move.

In fact, he has saluted the ­recruitment of Spain international Santi Cazorla, who has impressed his new colleagues in training.

Sources close to Old Trafford ­insist United believe they will get their man but manager Sir Alex Ferguson is adamant their ­valuation of the player at around £15million is ­justified.

Arsenal will not accept a move at that kind of price and Wenger is adamant he wants £25m for the Dutchman.
