Kenny Dalglish has backed Roy Keane in his war of words with Chelsea manager Jose Mourinho, insisting he was right not to shake his hand after walking off early in Blues' 3-0 win over Aston Villa.
"I probably wouldn't have shaken his hand, either, if I had been in the same situation as the former United skipper." Dalglish told The Mirror.
"Mourinho is at the top of the tree at the moment. You can get away with a lot of things when you're in his position.
"But maybe he should remember the old adage about being nice to people on the way up because you might need them on the way down.
"If things go a little wrong for him at some point in his career, he may find there are those who are keen to pull the ladder away from under him as quickly as they can."
Mourinho, with just minutes left on the clock, went to shake the hands of both Paul Lambert and Roy Keane but had no success. Both snubbed the Portuguese manager, and Lambert even proceeded to point to his watch.
The situation has become a hot-topic recently after Roy Keane, who is currently plugging his newly released book, opened up a war of words with the former Champions League winner.
Keane admitted he was unimpressed with Mourinho because the game was still going on, labelling him a 'disgrace'.
"It's disgraceful,' blasted Keane.
"I've seen him do it to other managers, it is a disgrace. The game is still going on. You wouldn't do that on a Sunday morning, you would get knocked out."
