Neil Lennon has explained why he expects Shane Duffy to bounce back from a tough week.

The Albion centre-back has come in for criticism from demanding Celtic supporters after defeats by Rangers and unbeaten Serie A leaders Milan.

Lennon believes the unusual nature of this summer and a hectic run of games for club and country - plus some emergency dental treatment - have not helped his on-loan defender.

The Celtic boss said: “He played three games for Ireland then had an abscess in his mouth that was giving him a lot of pain.

“He flew back into Glasgow last Thursday and had some emergency dental work. Then we had to roll him out there on Saturday against Rangers.

“He played on Thursday but we’re curtailed in that he’s got no Nir Bitton, Chris Jullien or Hatem Elhamed beside him.

“In the main, his performances have been pretty consistent. I know he’s under a bit of scrutiny because people are looking at him for some of the goals we’ve lost, but we can’t pinpoint that on Shane. It’s a collective effort.

“As the season unfurls and goes along, he’ll play a huge part for us.

“Shane’s a good type and he will revel in it eventually. But he’s only just in the door.

“He’s been thrown in without any real pre-season. He’ll get better and better — and he’ll be a stalwart for the team.

“The criticism of the team is justified at times, I get it. But some of it on individual players is unfair."
