Chelsea manager Jose Mourinho silently seethed as his side dropped points on the opening day.
The Blues boss refused to offer an opinion on Thibaut Courtois' dismissal by Michael Oliver when asked on Sky Sports, but was visibly angered as a series of decisions went against his men.
The Belgian goalkeeper was sent off in the second half after tripping Bafetimbi Gomis, and the resultant penalty handed Swansea the equaliser at 2-2.
Then in the dying stages of the game, Ashley Williams clashed with Diego Costa on the edge of the box but nothing was given - exasperating the Blues boss.
And Mourinho was insistent that the defending champions would have come out on top had they finished the game with their full compliment of players.
He told the BBC: "They didn't have chances against 11. The team was playing very, very well in the first half. In the second, in one minute, it was a penalty, red card and the goal - 2-2.
"If you have 10 men and are winning you can defend well and try to find a strategy but to play with 10 men and try to win the game is more difficult.
"I would say we were the best team with 11 players and with 10 we fought hard."
