Roberto Mancini: "I'm extremely sorry for Ben Arfa, who is an extraordinary player.
"I sincerely hope he recovers speedily.
"De Jong plays with grit, but he is not dirty. He tackles hard, but never intending to hurt.
"Last Sunday it was a playing accident. The referee saw it all, and did not even award a free kick against him.
"As to the Dutch coach, I am not going to interfere with his decisions. [The tackle on Alonso] was out of order, and it was uncoordinated in the extreme. But I hope that referees continue to evaluate him with fairness."
Chris Hughton: "Monday's operation on Ben Arfa's left leg was a complete success.
"The doctors have told us that the operation was very much a success, but it's important what happens next for Hatem.
"The leg has to be stabilised, and it's a long healing process for him, but we'll support him every step of the way.
"It's too early to talk about when he will come back really."
