Shay Given has welcomed LA Galaxy striker Robbie Keane on-loan to Aston Villa.
Given, who is back in training after his five week lay-off with a hamstring injury, is confident Keane can still be a threat at Barclays Premier League level.
He said: said: "It's great for Villa to secure a player of Robbie's calibre, even in the short term.
"I didn't know how fit he was before the last couple of days in training but he looks really sharp, to be honest.
"He's a big personality and he's a big-game player. I think even in training the lads have been very impressed with what they've seen."
Given added: "Some of the young lads here can learn from a guy like Robbie Keane. It's fantastic for them. I think the younger players will look up to him and learn from him.
"I also think he will cause Premier League defences plenty of problems when's given a chance to play.
"If you give him a chance, then nine times out of 10 he'll take it.""We're all delighted that he's here and I think he's just given the whole dressing room a lift.
