Issa Diop has praised new West Ham United teammate Samir Nasri.

The veteran Frenchman joined on a free transfer after his drugs ban was overturned.

The transfer was seen as a gamble, but Nasri has impressed since arriving.

Diop believes his quality on the ball is a very useful asset to the team.

"Samir is a very good player, everybody knows that," Diop said to the club's official website.

"He won the Premier League with Manchester City and was an international player, so everybody knows Samir.

"When I was younger, I watched him on TV when he played for Marseille and Arsenal, so everybody knows the quality of Samir.

"When I watched him in France, everybody said 'He is going to be a big player'. He was very young and he played with a lot of confidence and quality, so everybody knew he would be a big player."
