But when pressed over whether United suffered from a hangover in their defeat to City, Mourinho was unequivocal.
After the match, which put City 11 points clear of United at the top of the table, Mourinho had complained that United should have been awarded a late penalty when Ander Herrera tumbled under a challenge from Nicolas Otamendi. "They now have until 6pm on Friday 15 December". It was only his second Premier League goal in 10 games. They have wonderful players, they have a fantastic coach, they have lots of good things.
Mourinho said on Tuesday: 'The only thing I can say is that for me it was just a question of diversity - diversity in behaviours, diversity in education.
"Then is normal, physically he was feeling the cramps were coming, Eddie was not far from me and understood that, so they tried to force a little bit from that side, I had to bring Ashley on to protect the team and Luke".
City manager Pep Guardiola, meanwhile, defended his team's celebrations, but added that he was sorry if they had offended anyone.
Mourinho said: "It is only over in May".
"Very good, I think both", Mourinho said.
'I'm not saying first or second choice, he's an option, ' he said.
"If we were not correct than I apologise to all of Manchester United". Lukaku looked particularly drained in the closing stages of the Bournemouth game, but dropping him having just maybe regained some confidence after heading home his 14h goal of the season doesn't seem likely.
'We were so happy, we won a derby.
'Our intentions were to celebrate, inside the locker room, our happiness because we were happy. If in that way we offended United - not just one player, not (just) Jose - then I apologise.
