Brendan Rodgers is unsure whether to risk Scott Brown in Celtic's League Cup final against Aberdeen at Hampden Park on Sunday.
Brown came on as a late substitute on Thursday as the Scottish champions edged to a 1-0 Europa League victory against Rosenborg in Norway.
However, as Celtic have a hectic schedule in December, Rodgers is keen to use Brown sparingly.
The former Liverpool boss said: "Scott is an important player but we'll always pick the team to try and win. It's a busy month for us and a busy period, so he'll feature at some point.
"It was nice for him to come in and help us to close out the Rosenborg game, which he did really well. It's good to see him back. He's an important player for us but he has a brain. He's not silly."
Celtic extended their stay in Trondheim after Thursday's match in a bid to be fully rested before the cup final.
Rodgers added: "One of the key things is sleep when you are recovering.
"If we'd gone back on Thursday night it would have been the early hours of Friday morning and the players would then have had to travel back to their homes. They might not have got back until about 3am."
Rodgers' team have completed the domestic treble in each of the last two campaigns and the Bhoys are 1/7 to beat Aberdeen and secure their seventh successive domestic trophy. The Dons are available at 9/2 to lift the trophy.
