The midfielder, who had been sidelined since February, featured for 61 minutes as the Hoops eased to victory ahead of the presentation of the Clydesdale Bank Premier League trophy.
He said: "It's a special day, to do it at home means a lot.
"We've two games left before the cup final and we showed we're sharp, we're looking forward to it.
"I felt fine, it's 60 minutes under my belt and hopefully another game next week as well.
"It has been a nightmare. I am not the best spectator in the world. But as everything has been going so well recently I joined in with the lads last week in training.
"I didn't know I was going to start. I am a good couple of weeks ahead of schedule."
Goalkeeper Fraser Forster added: "It's been a hard season's work and it's the best way to finish the season, and obviously we've got the cup final to look forward to.
"We've probably exceeded expectations in the Champions League really and we've won the league comfortably, we've not really got out of third gear in the league but we've done the job comfortably."
