Speculation has grown that Owen Coyle will be unveiled at Parkhead by the end of the week.

Coyle is reported to have held talks with Celtic chief executive Peter Lawwell shortly after leading Burnley into the Barclays Premier League.

And his work has not gone unnoticed among the Celtic squad as defender Gary Caldwell's brother, Steven, is an integral part of the Clarets team.

Celtic striker McDonald said: "He's done a fantastic job.

"We've kept a close eye on Burnley this year as well because Gaz Caldwell's brother plays for them, so we've been hearing about Burnley for the last 12 months.

"We've seen a lot of them on TV and they've played some great stuff at times. It's not for me to comment on who's going to be the next manager - it's not my decision.

"I'll just be happy to pull on the Hoops again next year and work as hard as I can for whoever that is."

The former St Johnstone manager had been instantly installed as one of the favourites to succeed Gordon Strachan, whose resignation was announced during Burnley's play-off victory over Sheffield United on Monday.

The 42-year-old is now the runaway favourite amid reports that he has been offered the job.

Coyle was talking to the Burnley board today over an improved contract in a meeting arranged before the Celtic vacancy arose.

But there is no question the Celtic role will now top the agenda, despite Burnley's promotion to the top flight of English football following a 33-year absence.

Burnley though insist that Celtic have yet to make their move, officially at least.

"Contrary to widespread speculation, Burnley Football Club has not received any official approach from Celtic for the services of manager Owen Coyle," a club statement read.

"Nor will the club welcome any approaches for Coyle, who remains under contract at Turf Moor."

Coyle's lifelong allegiance to Celtic is well known and this is likely to pull him towards Parkhead rather than a shot at the Premier League.

The former Republic of Ireland international has previously spoken of his regret at missing out on playing for the club during a career which took in the likes of Airdrie, Bolton, Motherwell and Dundee United.

This opportunity to manage his boyhood heroes may be the only one that comes his way.

As well as promotion, Coyle took Burnley to the Carling Cup semi-finals and the last 16 of the FA Cup during his first full season in charge.

Former Celtic skipper Billy McNeil, who had two spells in charge of the club, believes Coyle's background as a supporter would help his cause.

"I think it helps," said the Lisbon Lion.

"The very fact that the fans anticipate that and would want that indicates that it would make the job easier."
