The striker joined Everton on loan at the start of the 2012/13 season, sparking speculation there had been a fall-out between Lukaku his parent club manager.

However, the Belgium international, who has scored eight goals in 13 appearances for Everton, insists he has no problems with Mourinho.

Lukaku explained his desire to play regular first-team football to develop his game was behind his loan move and confirmed he requested the switch after spending last season with West Brom.

"I'd first said I wanted to stay at Chelsea during the summer," he told Sport Voetbal magazine.

"And then I felt I had to leave to play more. It was my goal to do better than last season.

Special

"I've had Jose Mourinho as a coach for two months," he added. "Something special.

"He's building the foundations of an unbeatable machine again. We didn't have problems."

Lukaku found further respect for the Portuguese tactician after Mourinho received his request for Premier League football with understanding.

He went on to say: "He wanted me to stay and asked me why I wanted to leave.

"In some interviews my words were twisted, but the truth is that he accepted to let me leave.

"He did understand what I wanted. That's what I really appreciate in him."

The centre-forward has stolen the headline during his time at Everton and the 20-year-old is focused on returning to Chelsea at the end of the season as one of the best in his trade.

Best in the world

"Am I getting ready for Chelsea next season?," he asked rhetorically. "Yes, why else would I have signed a contract for five years?

"I will return to Chelsea as one of the best strikers in the Premier League."

Topping the Premier League Golden Boot race would not suffice for Lukaku, however, who wants to join the world's elite and highlighted Liverpool's Luis Suarez as one player he aspires to emulate.

"I still want to become one of the best strikers in the world," he expressed. "I hope that you can put me in line with [Edinson] Cavani, [Zlatan] Ibrahimovic, [Robin] Van Persie, [Luis] Suarez and [Robert] Lewandowski in two years' time.

"I analyse them all. I look at their movements. The presence of Ibrahimovic, the left foot of Van Persie, the right foot of Cavani, the movement of Lewandowski and the dribbles of Suarez.

"He is that unpredictable. In three years of the Premier League I haven't seen anyone doing what he did."
