Kelechi Iheanacho showed an "elite mentality" by putting in the hard yards just two days after Celtic beat Hearts to win the league.
The Nigerian striker played the second half on Saturday as the men from Glasgow's east end came from a goal down to win 3-1 and clinch the Premiership, with late goals from Daizen Maeda and Callum Osmand.
Several members of the squad were seen out enjoying themselves in Glasgow, but they do still have a huge game this coming weekend. Martin O'Neill's men can clinch a memorable double if they can overcome Dunfermline Athletic in the Scottish Cup final.

And Iheanacho was clearly conscious of that as he got straight back to work with a one-to-one coach on Monday.
Coach Kwaku Mhemeng shared clips of the 29-year-old taking part in finishing drills on his social media and wrote: "Champions on Saturday, back in work Monday. Elite mentality."
Iheanacho has had a huge impact as a substitute in the closing weeks of the title-winning campaign, but his lack of match fitness has meant he still hasn't been called upon to start games despite a clamour from fans.
