Neil Lennon admitted Celtic defender Kristoffer Ajer has improvements to make after he made a mistake in conceding a penalty against Rennes, but overall was left praising him for his performance.
The Bhoys secured an impressive 1-1 draw away to Ligue 1 opponents Rennes on Thursday night.
Ajer made a mistake in the first-half with a mistimed challenge on M’Baye Niang in the box, with the striker then converting the spot-kick.
But the Scottish champions responded with a Ryan Christie penalty in the second-half to earn a point in the first game of the Europa League group stages.
The second meeting with Rennes at Parkhead is set to be a lively affair, as substitute Vakoun Bayo was shown a red card in stoppage time for a second booking.
There are also home and away fixtures left to play against Lazio and CRF Cluj in an intriguing group.
Celtic manager Lennon mentioned Ajer after the result on Thursday and he was mainly positive about him.
“It was a penalty and it’s something Kris needs to work on a little, rest of his game again was outstanding,” Lennon said, as quoted by the club’s official Youtube account.
Ajer did make an individual error that Celtic can’t afford too much of on the European stage, but he’s an ever-present in the team and an important player.
The 21-year-old is a colossus centre-back that was mainly impressive in defence against Rennes and a movement of madness was the only flaw.
It helped that he had the commanding Christopher Jullien alongside him and they look a formidable duo in the making.
