Bolton Wanderers boss Gary Megson could not understand why Jlloyd Samuel was sent off in Saturday's 4-0 home defeat to Premier League leaders Chelsea.
Samuel tripped Didier Drogba in the penalty area just before half-time, resulting in a straight red for the Wanderers full-back, and Frank Lampard duly sent Jussi Jaaskelainen the wrong way from the spot.
But the decision infuriated Megson, who said:"It was a soft penalty, I have seen them given and not given.
"Samuel didn't do anything wrong other than to try to get at the ball, I have no problem with Drogba, who took the ball across his body and there was going to be contact.
"The referee had a decision to make, and when you get Peter Walton, penalties and Bolton there is only one thing that is going to happen.
"Any of the top-six teams playing against ten men and with a lead would not quite have a stroll, but they would do the right things at the right time and that is what Chelsea did.
"They made nine changes from midweek, and they had plenty to spare.
"But there has to be some reality here, we were playing against a club who have spent £200million on players, they are one of the best teams in the world and they will have an advantage.
"They looked very strong, very motivated and they wanted to win everything put in front of them.
"We may have been beaten 4-0, but we were terrific. We matched them in their diamond midfield formation, we didn't struggle against it."
