Wigan Athletic boss Roberto Martinez admits he was surprised by Mohamed Diame's stunning effort in their 1-1 draw with Sunderland on Saturday.

The visitors deservedly took the lead through Diame's stunning 20th-minute strike, which came as a pleasant surprise to manager Martinez.

Martinez said: "I am sure he was surprised as well because I haven't seen him striking the ball like that before.

"But he deserved that because he works extremely hard for the team.

"Momo is settling in the Premier League with ease, which is a great compliment because playing in that position, it is full of athletes in the Premier League and he is enjoying his football.

"To see him striking a ball as clean as that, it was a great finish. I don't think you will see a better finish today in the Premier League."
