Tottenham striker Robbie Keane fuelled speculation that he would be interested in a move to Celtic after praising new Bhoys boss Gordon Strachan.
"He's the best manager I have worked under," said Keane after scoring the Republic of Ireland's winner in Jackie McNamara's testimonial at Celtic Park.
"I'm sure he's going to do a tremendous job - he gets the best out of players and knows the game inside out.
"I'm a Celtic fan, and I have said that one day I would like to play for them."
Keane seems to have dropped down the White Hart Lane pecking order under Martin Jol.
And, with just the year remaining on his contract, speculation is mounting over his future.
He worked with Strachan during his days at Coventry.
When asked about the prospect of moving to Glasgow, Keane said: "I've been linked with moves to every club this summer.
"At the end of the day, I've got one year left at Tottenham, and I am happy there but, if things change, then who knows?
"If the manager or chairman told me I was no longer wanted at Spurs then I am going to have to consider my future."
