Spurs clash the real test for United says former Red Devil.
Solskjaer has enjoyed a perfect start since replacing Jose Mourinho at the Old Trafford helm.
Dimitar Berbatov has given his backing to Ole Gunnar Solskjaer, saying Manchester United should make the Norwegian their permanent boss.
Solskjaer has been a breath of fresh air at United, winning his first five games on the bounce as caretaker boss.
And, former Red Devils frontman Berbatov believes Solskjaer’s positive impact cannot be ignored, adding he is the right man for the job.
“If United keep going like this – and there's no reason why they will stop performing – the job will surely be his,” he told the Mirror.
“He's doing a great job. By the end of the season, as long as they keep playing like this, they should give him the job whether or not they finish in the top four.
“If they don’t, I'm sure that another Premier League team will give him the job. He's making his name once again in the top-flight and it’s great for him.
“When a club legend becomes your manager, he automatically gets the attention of the players, purely because he had been there and done that.
“When you are in the position of Ole, having scored so many goals and won so many trophies, he gets the attention.
“He doesn’t need to yell or scream to prove anything, he just gets it.
“From that point on, he needs to show them that they need to trust him, that he knows what he’s doing and, judging by the results and the way they play, it’s obviously working.”
Spurs host United on Sunday and the 37-year-old - who left the north London club for Old Trafford back in 2008 in a deal worth £30.75million - said: “This is the first real test.
“At some point a loss is going to come and then it will be interesting to see how the new boss is going to react to the first one.
“Unless they don’t lose to the end of the season, of course. That really would be unbelievable.
“If Spurs can overcome the tiredness in their legs, they have a great chance of winning again.
“But United will be so confident after five wins in a row and they can win this if they play smart and exploit any fatigue Spurs might show.
“It’s going to be entertaining, I’m sure. A defeat for either would be a damaging blow to their season-long goals.”
