Celtic captain Neil Lennon admits the lure of the Champions League has convinced him it would be hard to leave the club this summer.
Lennon's contract expires soon after the season ends, and the Northern Irish midfielder will be 36 by the start of the 2007-08 campaign.
But after Celtic's run to the knock-out stages in Europe this season, Lennon is keen for more Champions League action and plans to discuss his future with manager Gordon Strachan.
'We will see what the club have to offer - if they are going to make me an offer,' he said.
Lennon was signed from Leicester for £5.75million by former boss Martin O'Neill in 2000, the pair having previously worked together at Filbert Street.
He has since been a mainstay of the Celtic side, and explained: 'I have enjoyed this year; it was totally unexpected. We could have even gone a bit further.
'It would be difficult to give all this up and give the captaincy up, too, because that means a lot to me. I'm very proud of this team and getting through to the last 16 was a monkey off my back.'
Meanwhile the referee who turned down two penalty appeals from Celtic during Wednesday's 1-0 defeat to AC Milan has defended his decisions.
Paolo Maldini handled the ball on the edge of the six-yard box in the early stages, and the other appeal came when Shunsuke Nakamura fell under a challenge from Massimo Ambrosini.
Konrad Plautz said: 'I firmly believe Maldini put his hands up instinctively, not to deny a goalscoring opportunity. The key phrase here is that it was ball to hand, not hand to ball.
'There was contact between Nakamura and the defender. But it was a normal kind, something that happens when two players are running for the ball, not a foul.'
