Giggs revealed: "I think the last time was at Arsenal the season before last when Thierry Henry scored in the last minute.
"The manager went into one and I think some of the foreign lads thought 'bloody hell, what's going on here? This is not what I signed for.' It was funny."
Giggs also told GQ: "The manager would watch me when I was 13, 14, and I'd get the hairdryer treatment. My attitude was always 'right, I'll show him he's wrong.'
"He'd shout everything he could think of as loudly as he could. Telling you how badly you'd played and you'd never play for the club again.
"Dropping you was as bad as it could get. He'd never have a go for missing a chance or an open goal.
"But if you weren't working hard enough or had a shot when someone else was in a better position to score, they were the worst crimes imaginable to him.
"I used to be scared of it, still am I suppose. He can still drop you, as he did last season. The good thing now is I get 'rested.' It's the best thing about getting older."
