Sunderland boss Martin O'Neill admits he doesn't get along with Arsenal boss Arsene Wenger.
O'Neill has long been furious at Wenger's accusation of his long-ball tactics - and hit back by telling him he was in danger of being carried away with his own self-importance.
O'Neill admitted: "I always have a difference of opinion with people.
"I don't think Arsene has ever taken up the offer of a post-match drink and I've absolutely no problem with that whatsoever, none at all. But it's there if he wants it.
"I understand it's more a British habit and something the foreign managers didn't really share before coming to the Premier League.
"I saw Tony Pulis after the game last week and Alex Ferguson always invites you into his office. But, in fairness, I'm never really sure about it anyway. I think the foreign mangers might have the right idea.
"It's a bit of small talk after the game. If you've won, you're delighted and if you've lost, you can't wait to get out of the room." "I don't always see eye to eye with him. But then I don't think he always sees eye to eye with anyone.
