"I didn't swear at the referee or anything," the Black Cats boss said after the game.
"All you want when you play one of the big boys is a bit of fairness and I don't think we got that today.
"Don't take anything away from Chelsea though. There's no shame losing to a team like that.
"When we were 5-0 down with 35 minutes to go and Didier Drogba started warming up, I wished someone would fast forward that clock.
"But my players kept going. It's been a tough week for us, particularly having to come to Chelsea after they'd had a defeat.
"We knew there'd be a reaction and unfortunately we were on the end of it.
"I've never had a problem in my career in praising the opposition.
"I wouldn't say I'm happy, I'm just not as angry. I'm relaxed."
