Jack Collison admits he's impressed by the quality of experienced West Ham striker Diego Tristan.
The Spaniard struck the winner against Stoke City last week and midfielder Collison told whufc.com: "It wasn't a bad strike was it? A player like Diego Tristan has been there and done it and can bring that sort of quality to our team. It was a great strike and fair play to him.
"He's obviously that little bit older now, but there's no doubting his ability when you get the ball into his feet. He showed that at Stoke and almost did it again when he dinked one over the 'keeper [in added-time, only to see his shot bounce narrowly wide of the post]. We've got three games left and I'm sure he'll keep producing the goods."
