Celtic manager Martin O’Neill has admitted his club are interested in signing Brazilian World Cup winner Rivaldo.

“Like anything else we’d prefer to keep these things quiet – we have been linked with so many players,” said O’Neill.

“But the truth is when somebody like Rivaldo becomes available you have got to be interested.”

Bolton have offerd Rivaldo a deal but are still waiting to hear back from the Brazilian.

“Perhaps this is more about the agents talking than anything else during the last couple of weeks.

“One of the things which is appealing to me is getting in short-term players,” added O’Neill.

“Bolton have done very well in getting some top-class players to the football club.

“So we have got to be looking at that type of player.

“I wouldn’t want to be giving any bookmakers odds and it might be a move of great difficulty – but he is a class player that we would be looking to buy.”
