Tottenham legend Glenn Hoddle insists Arsenal manager Arsene Wenger is capable of tearing strips off his players when needed.
Hoddle wrote in the Mail on Sunday: "When Arsene Wenger was a young manager, at the start of his career, he was extremely passionate. If we had let him down in a game at Monaco, he would let you know in the strongest way.
"The dressing-room could get fiery. I remember bottles being thrown — plastic ones, that is — and a stream of angry French being directed at the team.
"Mark Hateley and I were the two designated foreign players and would be a little a bit outside of it all, because it was in French. But there was no danger of misunderstanding the general message. If we were not doing what he had asked, he would show it.
"Once he had finished on the team in French, he would turn to Mark and I and, perhaps because he had to use English, it wasn't quite as angry but he would be cold and clipped with us, telling us what he wanted.
"Arsene has changed quite a lot over the years and I understand he is a lot more controlled in the dressing-room these days. But don't be misled. This is a man who hates losing and will have been seething at the defensive performance on Tuesday night against Olympiacos."
