Chelsea striker Olivier Giroud says Arsenal's players are enjoying life under Unai Emery.

Giroud spent six years at the Emirates before switching across town to Stamford Bridge.

He still keeps in contact with some of his former teammates and has heard positive things about the Spaniard.

"I think Emery has settled well in the club, the players like him, the way they are training, his philosophy of the game," Giroud told ESPN.

"I spoke with some of them and they are quite happy, but you don't forget what Arsene Wenger achieved in this club.

"He basically built this club – if you take the different teams that used to train under Wenger, there were some unbelievable teams.

"We need to be patient with Emery and I think he will do very well at Arsenal. I'm not sure they're better than before [yet], but one thing for sure is they've got a nice future."
