Manchester United were interested in the forward but will now focus all their attention on signing Alvaro Morata from Real Madrid.

Mourinho sold Lukaku to Everton back in 2014 when he was in charge at Stamford Bridge.

But Starsport understands the Belgian is set for a return to the Blues under Antonio Conte as their leading striker.

That’s after the Italian manager told Diego Costa he is free to leave the club this summer.

Mourinho has been monitoring Lukaku ever since he left Chelsea and was ready to bring him in at United.

Red Devils supremo Ed Woodward held talks with super agent Mino Raiola over a possible switch but the 24-year-old has decided he wants to move back to London.

Lukaku was in stunning form last season, netting 25 goals in the Premier League.

United have since turned their attention to Morata and look set to spend £70m on the Spaniard.

Mourinho is said to believe he can form a good partnership with Paul Pogba as the two were previously together at Juventus.

United have signed one player so far this summer, centre-back Victor Lindelof from Benfica as they prepare for a return to the Champions League.

Mourinho is also interested in Ivan Perisic and Nemanja Matic to strengthen his midfield.
