Cech revealed the 33-year-old had been equally calm in the dressing room after what was his first league defeat in 17 months.
"He was no different to us," the Czech Republic star said. "We know we didn't take our chances in the first half and that we didn't play well.
"But we have to be very positive about the way we came back and fought to the last second in the second half - that is basically what he told us as well.
"We know that we lost the game but we did enough to get something out of it.
"Every game, we are improving. The score doesn't reflect how we played. Some people could say that 3-1 looks an easy game for them but that was not the case.
"We conceded three goals in the first half which is not ideal.
"But if you count the chances, they scored from the free-kick where there was a doubt over it being offside, then a wonder goal from Nani and then a lucky deflection for Wayne Rooney's goal. That was it more or less.
"You could see that this was a game between two teams in form and the difference was that they took their chances and we didn't take ours."
