Former Manchester United midfielder Quinton Fortune has confirmed that he met with representatives from Celtic on Friday — but stressed talks were strictly informal.

The South Africa international was released by United this summer after failing to hold down a regular first-team place at Old Trafford following a knee injury.

But, after receiving an invite from ex-United team-mate Roy Keane, the 29-year-old visited Glasgow to have a look at the club.

Fortune told the Sunday Mail: "Keano phoned me up — we were friends at United.

"I was in Glasgow on Friday to see things for myself and it was terrific.

"Celtic are one of the greatest clubs in the world and the history and passion around the place is unbelievable.

"If you asked any player in the world to play there, they'd do it.

"I don't want to make too much of a comment or be disrespectful to Celtic because I haven't had a medical or signed anything.

"But, from what I saw of them on Friday, it would be an honour to play there.

"There are a few clubs involved but I can't say too much at the moment because I don't want to come across as being cocky or disrespectful to any of them."

Celtic chief executive Peter Lawwell is set to continue talks with Fortune's agent, Francis Martin, next week.

But the player's representative also maintained the trip north was not official after meeting Celtic boss Gordon Strachan.

Martin said: "Nothing was discussed about contracts, finances or anything.

"It was just a cup of tea and a look around the place. Quinton flew up and flew straight back.

"But we will carry on talking through this week when Peter Lawwell is back."
