And the Villa boss hasn't ruled out the possibility of trying to tempt the Finland international signing for his side when the transfer window opens again in January and Forssell has completed his initial four months on-loan at Blues from Chelsea.
“I like him yes, but I’ll say no more. He’s young and I think someone like him would improve us immensely, O'Leary told his clubs official website, www.avfc.co.uk.
“I don’t think there’s many around like that, that are there to be got.
"He’s young and Chelsea, with the abundance of the stuff they’ve got there, it’s not like going to another club where that’s their only striker and they can’t lose him.
"I knew he was going to come out and I think he would have been good for us.
“I haven’t got a clue if we can pursue that in January, but I think he’d be good for here.”
