Since Ole Gunnar Solskjaer took over from Jose Mourinho as caretaker manager of Manchester United, the Norwegian has turned things around at Old Trafford, picking up 32 points in the Premier League since he took charge.
The club's dramatic 3-2 win over Southampton at the weekend meant that Solskjaer's side are unbeaten in 12 Premier League matches.
But their former manager Mourinho isn't exactly convinced that Ole will improve United in the long-term.
He may have more points in his first 10 games than any manager in Premier League history but the former Real Madrid and Inter Milan boss has his doubts.
When talking about Fulham's decision to get rid of Claudio Ranieri at the end of last month, Mourinho compared the situation with Manchester United's decision to sack him.
"Can [Fulham] get a better manager than Claudio? Not at all," Mourinho told beIN Sports.
"Can you compare the experience between Claudio and Scott, who is going to coach a team for the first time? Not at all.
"But sometimes in football, and you have the example with my former club (Manchester United hiring Solskjaer), that sometimes changes on the immediate.
"I don't believe too much in these changes in the long term - but these changes on the immediate, there are sometimes some positive results."
Mourinho appears to be suggesting that long term, Solskjaer's reign may not be as successful as short term.
Do you agree with Jose on these points?
