Celtic midfielder Roy Keane has revelaed that he may retire at the end of the current campaign.

The former Manchester United player is contracted to stay at Parkhead for another season but a long-standing injury may lead to the 34-year-old hanging up his boots a the end of the season.

He said: “When I signed for Celtic I did say it would be best to maybe look at things in the summer.

“They were keen for me to sign for the extra year, which I did. I will see how my hip is bearing up in the summer.

“I am due to go back to the hip specialist in the summer.

“It is important to be fair to myself and the club if it is affecting me.

“I will weigh it up then but there are no guarantees about next season, I have to say.”

Keane revealed in February 2003 that he may have to undergo a hip replacement once his playing days were over.

“Since having the surgery in 2002 I have regarded every season as a bonus but I have got to look at the long-term side of it and see what is best for me and my family,” added Keane.

“Over the last few months I have always put football first but, come the summer, I need to look at what is best for my family.”
