It has not been pretty, with Tottenham scrambling points in unconvincing fashion, although a smash-and-grab 2-0 home victory over Manchester City in their last league game showed much about the galvanising effect Mourinho has had.
He also substituted Jan Vertonghen early in their FA Cup replay against Southampton, prompting Merson's comments.
"Tanganga's already in the dressing room, with Skipp", Mourinho said.
He said: "Contrary to some people who tell things that are not true - I am really happy at the club".
"Wolves and Sheffield United are fighting for the top four, [the managers] they can say no, and I understand if they say no but the reality is that they are". Difficult? Yes, but if it was not difficult it wouldn't be for me.
Jose Mourinho added that the fight for top 4 is not only between Tottenham, Arsenal and Chelsea, with teams like Wolves and Sheffield United giving them a run for their money.
"I'm seeing real green shoots of recovery within the players and knowledge of how each other plays".
"He looks like he's thinking: 'What have I done coming here?' You don't see him high-fiving ball boys now do you?"
"From time to time I like to experiment, commented on Sky Sports, the changing image of Jose Mourinho". I want to start working with them in July'. He's Grumpy Mourinho again.
Tottenham will return to Premier League action after the winter break with a trip to relegation candidates Aston Villa at Villa Park on Sunday afternoon. And I don't see how he's improved them at all. Even the warm-ups. I can see what TV and video don't give me. "I couldn't miss the opportunity". "He's played under Jose twice and they celebrated a lot of success, so that respect is natural".
"But not for me".
