Romelu Lukaku made it two goals in two games for Manchester United in the club’s 2-0 victory over Manchester City last night.Okay, so it’s only the pre-season. But there’s still plenty of reasons to be excited - his finished against Man City was just class."I couldn't be happier with what he's doing,” Jose Mourinho said about the Belgian, per the Independent, “and I could not be happier we managed to sign him before the pre-season.”Lukaku has the potential to become one of the world’s best strikers, so it’s no surprise that Mourinho is so pleased to have signed him.There was interest from Chelsea, and at one point the Blues were in pole position to sign the forward, but Lukaku ended up signing for Man United in a £75 million deal from Everton.And in a fascinating interview with the Daily Mail, Lukaku’s childhood friend Vinnie Frans has revealed just how hard Mourinho pushed for the 24-year-old.“As a child, it was all about Didier Drogba,” Frans said. “When he scored goals on the street, it was the Drogba celebration with the arms. But he just had one call from Antonio Conte.“Manchester United came with three different contract offers and Chelsea did not present one. United wanted him more and that’s the reason he chose them.“Rom had it clear that he wanted to start pre-season properly with a new team.“Chelsea kept waiting and waiting so he thought ‘United have come with a good offer, Mourinho has great ideas and he was 100 per cent sure Mourinho wanted him’.“At first he was like ‘Let me wait a bit and see what other clubs are doing’. But United wouldn’t take no for an answer.

“After the second offer he thought ‘Hmmm, they really want me’. Then it was a third time and it was ‘Hmmm with a few ‘M’s’ then the fourth came and it was ‘OK, I’m going to Manchester’.

“Pogba was talking up United but it was always going to Romelu’s own decision.”  

What Lukaku said when Mourinho asked him for a decision

Lukaku was in Los Angeles when he received another call from Mourinho. At this point, he had made his decision.

“In LA, Jose called him up again and said ‘Have you made a decision?’ He said ‘Boss, I’m coming to United’,’ Frans added.

You can understand now why Lukaku decided to sign for Man United instead of returning to Chelsea.

Mourinho made it clear how badly he wanted him - and wouldn’t give up until he was a Red Devil.
