Newcastle United boss Alan Pardew revealed Andre Villas-Boas apologised to him over the behaviour of Chelsea's staff during yesterday's defeat.
Pardew was less than impressed by Chelsea fitness coach Jose Mario Rocha, who celebrated Kalou's strike in front of the Newcastle bench.
He said: "The manager apologised for that. He carried himself with dignity today because he was under a lot of pressure, their manager.
"But his staff let him down today and I am sure he will be having a little word in his ear."
