Manchester United have signed striker Romelu Lukaku from Everton for an initial £75m on a five-year contract.

Champions Chelsea had matched the Red Devils’ bid, but missed out on re-signing their former player.

“Romelu is a natural fit for Manchester United. He is a big personality and a big player,” said boss Jose Mourinho.

“It is only natural that he wants to develop his career at the biggest club. He will be a great addition to the group. I am really looking forward to working with him again.”

Lukaku, whose contract includes an option for a sixth year, said: “When Manchester United and Jose Mourinho come knocking at the door, it is an opportunity of a lifetime and one that I could not turn down.

“I cannot wait to run out at Old Trafford in front of 75,000 fans.”

Lukaku sent a farewell message to Everton on Monday in which he thanked the club and said it was “an honour” to play in front of their fans.
