The former Celtic player was not happy with the performance of his former club this week.
Celtic will play in the Europa League proper this season after failing in qualification for the Champions League earlier this week. They were dismissed by Swedish side Malmo on Tuesday night, after losing 2-0 in Sweden.
Now, a former Celtic player and football legend, Roy Keane has had his say on the exit – and he was not impressed.
Keane, who played for Celtic briefly at the end of his career, is more synonymous with Manchester United after spending 12 years at the club – the majority of which were as club captain.
Now the assistant manager of Republic of Ireland, he told the Daily Record that the experienced players in the Celtic side in particular should be disappointed in their performance:
"Playing for a big club like Celtic, the players should not be scared of anybody. It's an honest assessment from the manager, but if he's talking about the younger players, then he should look at some of the senior players who went missing.
"They should have been helping their younger team-mates. Every player in the team should take a look at themselves, not just the younger ones."
It comes after Ronny Deila made a point about his team being ‘scared’ in the Malmo fixture. Keane however seems to be clear in his criticism.
He believes the likes of Scott Brown, Charlie Mulgrew and Kris Commons did not do enough to help Celtic’s younger talents perform to their full potential and push Malmo all the way.
In the end Celtic deserved to lose to Malmo and Keane, as a Celtic follower, was as gutted to see them depart the Champions League as anyone else.
Hopefully Celtic can do themselves proud in the Europa League instead.
