Celtic have already said they have no intention of allowing the striker to leave Parkhead in the summer but his comments could spark a scramble for his signature.

“A move closer to Wales is something I have got to consider at some point,” he said.

“I‘ve got two wonderful children whom I love and miss dearly and being so far away in Scotland is far from ideal.”

Hartson says a move to Swansea, the club he supports, could be on the cards one day.

Speaking in the League One club’s matchday programme, he said: “If you look at Roy Keane, he has fulfilled his dream of playing for his boyhood club.

“He may have come to Celtic near the end of a glittering career but he‘s still come at a time when he can add plenty to the team.

“I would like to do the same to Swansea one day – and when they say you should always go out at the top, Swansea is top for me.”
