Arsenal defender Shkodran Mustafi admits the squad isn't always a happy camp.

Mikel Arteta took charge in December following the sacking of Unai Emery, who reportedly alienated a number of key members of the squad with his methods.

"Each one of us has benefitted from this arrival," Mustafi said. "He has brought a very clear identity and a very clear idea of how he wants to play football, but at the same time he gives you space to make your own decisions because you are on the pitch and you know exactly what the coach wants from you.

"I think as well he has been listening into the changing room and listening to the players to find out why things were not working out before. Sometimes we don't realise how difficult it is to be a coach because you have so many people that you have to make follow your idea.

"Sometimes players are happy, sometimes players that don't play are not so happy, so it is not easy to have all on board and all agreeing with your ideas and philosophy.

"But he has managed to do that and in this short period it has been something very difficult to do, but he has done it. That is why we created a bit of momentum and we are heading in the right direction."
