ROY KEANE reckons Celtic are not learning any lessons from their experiences in the Champions League.

The Irish legend, who had a five-month spell at the Hoops in 2006, was highly critical of his old club after their 3-0 hammering from Bayern Munich.

Keane said: “It was a tough night for Celtic. It was always going to be a difficult game for them.

“It wasn’t just the goals they conceded, but the chances they gave up, players ball-watching and lacking concentration, not smelling danger.

“They gave up some easy chances – they were lucky it was only three.

”You talk about them learning, but from looking at Celtic over the last one or two years in Europe, they’re not learning.

“They’re making exactly the same mistakes against top opposition. To me, they’re not learning.”

Keane blasted Celtic last year for celebrating ‘as if they’d won the competition’ after beating Hapoel Be’er Sheva 5-4 on aggregate to reach the group stages for the first time in three years.
