Asked on Thursday if he had calmed down, Lambert said: "I was calm last night.
"I think there has been a lot made of me and Jose in the technical area. There was the odd little thing, but there was a lot of banter between us."
When it was put to him that Mourinho had said after the match that Lambert "complains with every decision", the 44-year-old said: "So did he. It is the same. The two of us shout at referees and officials and everything.
"I'm not going to go there and lie down, and neither is Jose.
"A lot has been made of me moaning - he does his fair share as well, just to let you know.
"It is not a problem. We had a bit of banter between us and I saw him afterwards. I like him and he is a brilliant football manager. There was never a problem."
