Kasper Schmeichel didn't quite look himself against Borussia Dortmund - and the Celtic keeper must 'be careful' he doesn't start to show his age.
That's the view of his former Man City teammate Richard Dunne who saw some warning signs in the shotstopper's performance. Schmeichel had a tough night at the office in the 7-1 defeat though he could hardly be singled out for blame on a night there were barely any pass marks in green and white.
It was a sobering defeat and a reminder for Brendan Rodgers' team that they have a long way to go before they're on the level of the Champions League finalists.
Former defender Dunne saw Schmeichel at City when he was just starting his glittering career, which saw him win the Premier League with Leicester and eventually land at Celtic as the heir to Joe Hart.
