Arsene Wenger has criticised Roberto Mancini's public pursuit of Samir Nasri.
The Arsenal boss has been angered by his Manchester City counterpart's admission that he is hopeful of signing the French playmaker in the next fortnight. Arsenal are desperate to retain Nasri's services in the light of interest from City and Manchester United even though he is in the last year of his contract and could leave on a free next summer.
Wenger selected Nasri for the draw with Hangzhou Greentown and afterwards told Sky Sports: "These comments are not allowed, it is against the basic rules of football and Roberto Mancini should be informed."
He added: "I don't spend my time on what other people say. We are focused on playing our football.
"What we want is respect. We will not comment on any players at other clubs. It is time football in England came back to these basic rules."
Asked about his move for Nasri earlier on Saturday, Mancini said: "I don't know in this moment, I don't know the situation but for Nasri it is difficult.
"I hope that we can buy because we need other players, and I hope that this player can arrive before the end of the month."
