Mourinho got one over on his former club on Sunday as Tottenham sealed a 6-1 victory over United at Old Trafford.
Solskjaer’s side had taken an early lead through Bruno Fernandes’ penalty but Spurs hit back and were 4-1 ahead at half-time, while Anthony Martial was sent off for the hosts.
Tottenham then added two more in the second half to complete a miserable afternoon for Solskjaer.
United are now under pressure to add to their squad before the transfer window closes on Monday, having only signed Donny van de Beek so far.
Asked if he had any sympathy for Solskjaer due to United’s lack of activity in the transfer market this summer, Mourinho said after the game: ‘I have sympathy for Ole because of the result.
‘I don’t remember that I lost by six but I’ve lost by five and lost by four, I know how it hurts.
‘I know that it’s very, very important that the winning manager behaves in a way where he shows sympathy.
‘Of course I want to win and of course I want to win by seven and not by six [goals], don’t get me wrong. But sympathy in our behaviour, today was him, tomorrow it’s me, and of course I feel sympathy for him.
‘But when I look to his team there was an evolution.
‘It’s not like he arrived here and the team didn’t improve anything.
‘The team is improving, they have good players, he bought lots of young players, they bought very good players.
‘If it’s true that Cavani is coming, Cavani is one of the top strikers in the world, and Manchester United is Manchester United, it’s not this defeat that’s going to destroy them.
‘I can imagine they are going to react like Manchester United always react.
‘So I feel sympathy for the result but apart from that, no sympathy because he has an incredible job, the players will stick with him, the feeling is that the players like him, the players are going to react, for sure.’
