Lukaku’s brace in Moscow took his tally to 10 goals in nine games so far this season, a record that even Mourinho admitted was amazing.
“He is having a great record but we know he is a very good player who will score lots of goal when surrounded by quality players,” Mourinho said.
“But I have to admit he is scoring important goals in almost every game.

The Portuguese then went on to praise the rest of the United squad.
“It is a great achievement but it is only possible with a good team.
“Without a good team it is not possible and the team is playing well. They are amazing numbers for Romelu. He is humble and wants to learn and improve all the time.
“I think ambition is there and I trust he can keep performing for us.”
“I think the performance can only be good for the team and the players,” he added.
“For the team confidence is good because six points in two matches in the Champions League puts us in a good position and for the players individually it is also good because we had very good performances.
“(Chris) Smalling and (Victor) Lindelof had very good performances, (Ander) Herrera has not started a match in a long time and had a good performance, so did Anthony Martial – and I am speaking about the players who are not starting matches.
“We have to keep our feet on the ground, stay humble and follow our direction because we are having a very good start to the season.
Mourinho may be keeping his feet on the ground, but the same cannot be said for Man United fans, who went crazy on social media.
Lukaku > Messi + Ronaldo

Lukaku has a terrible first touch. It keeps bouncing off him and into the net ?

Other fans made predictions about how many goals their man could get.
Lukaku is easily hitting 35+ goals this season if he stays injury free #MUFC

The player himself, meanwhile, is only concentrating on one thing.
"My target for the season? I just want to win trophies."
