That’s the accusation fired by former United manager Louis van Gaal.
Solskjaer replaced Mourinho in December after the Portuguese was sacked following a disappointing start to the season.
The former striker has been a revelation at Old Trafford, masterminding a stunning Champions League last-16 win over PSG and guiding his side back into contention for the top four.
Solskjaer is expected to land the gig permanently, something few people saw as a realistic option when he was appointed on an interim basis.
Mourinho was criticised for his defensive tactics and Solskjaer has managed to get the best out of his attackers by giving them more freedom.
But Van Gaal, who was in charge of United for two seasons, has defended Mourinho.
And Red Devils fans are likely to be angered by his comments, suggesting Mourinho is the reason for their recent success.
Van Gaal’s revelation comes amid news that:
“The main difference between Mourinho and Solskjaer is that Solskjaer is winning.”

“The coach after me changed to park the bus tactics and played on the counter,” he told the BBC.
“Now there is another coach who parks the bus and plays on the counter.
“The main difference between Mourinho and Solskjaer is that Solskjaer is winning.
“It is also true that Solskjaer has changed Paul Pogba’s position and put him into an area where he is much more important.
“But the way Manchester United are playing now is not the way Ferguson played.
“It is defensive, counter-attacking football. If you like it, you like it.
“If you think it is more exciting than my boring attacking, OK. But it is not my truth.
“They can also win the Champions League because they play a defensive system and it is very difficult to beat them, which, whether you like it or not, is the result of Mourinho’s work.”
