Celtic manager Gordon Strachan is confident Roy Keane will still be a Hoops player next season.
The 34-year-old midfielder only arrived from Manchester United in January but has since hinted that a long-standing hip injury could force him to retire at the end of the season.
However, Strachan told Sky Sports: 'I think I will have Roy next season. He loves it at the club and I can't see him leaving.
'I see people bowing to Teddy Sheringham and quite rightly because he's 40.
'At my club if you get to 33 or 34 you've got to move on. Why?
'Gary McAllister was a star at Liverpool and there are players playing at all sorts of ages.
'It's just fitness that counts. Fitness, speed, motivation - if you've got that then fine.'
Strachan is also looking to boost his squad, adding: 'We will try and bring players in, no doubt about that.
'We will look at our budget at the end of the season but nobody has been asked to leave this club.
'What we've got to try to do is add to the squad.'
• Roy Keane's testimonial on May 9 at Old Trafford seems certain to be a sell-out after Manchester United confirmed they have already sold 10,000 tickets for the clash against Celtic.
The tickets only went on sale on Monday and the early sales indicate the huge affection still held at Old Trafford for Keane despite his shock departure from the club in November.
Celtic have been allocated the entire 25,500-capacity North Stand for the game and are confident they will fill it.
The match, part of Keane's severance from United, is likely to net the former Republic of Ireland captain in excess of £2.5million in gate receipts, although it is believed Keane will donate the money to charity.
The 34-year-old has already indicated his intention to give 1,000 tickets away to local school children and United supporters' club branches.
