Callum McGregor believes Tuesday's gruelling workout against Paris St Germain was the perfect warm-up for Celtic's Champions League bid.
Neil Lennon's side were outclassed by Neymar and company at the Parc des Princes, with the French giants romping to a 4-0 win.
But stand-in skipper McGregor, who took the armband in the absence of injured captain Scott Brown, feels the friendly clash with the big-spending Parisians is just what the Hoops need as they get set for another assault on the group stages.
Celtic's opening qualifier on August 19 is less than a month away and the Scottish champions will have to overcome four opponents before they can take their place among Europe's elite.
But McGregor is sure his side will be more than ready for that quest having been pushed to the limit by PSG.
The Scotland midfielder said: "The Champions League is the level that we want to play at, so the PSG game is a nice taste of what could be.
"But we always know how hard it is to get there and that's the level that we have to reach.
"It was a very good exercise, 90 minutes in the legs, and good to see the opposition."
