Stoke City winger Liam Lawrence admits he's been convinced about a move to Celtic by Republic of Ireland teammate Robbie Keane.
Tottenham striker Keane had six months on-loan at Parkhead last season.
"Keano says it's an absolutely massive club with unbelievable support, stadium and training ground," said the Stoke midfielder.
"He rates it as one of the biggest clubs in Britain and I'm very excited about the prospect.
"I'd love to play in front of 60,000 and in the Champions League."
