Sunderland boss Roy Keane admits he was impressed by Wigan's Egypt striker Amr Zaki in Saturday's 1-1 draw.

"I'd never heard of Zaki (before this season) so someone's in trouble!" Keane joked. "It's always a gamble to bring a striker in but he's hit the ground running. It'll be intriguing how these players do over the winter months. He's got the physique for it. He took his chance and he's pretty sharp at the moment. The manager deserves credit because we all get sent different reports on different players and you've got to take the plunge."
