Sam Allardyce has urged Ole Gunnar Solskjaer’s Manchester United to make a swoop for Diego Costa this summer transfer window if Romelu Lukaku ends up departing the club.

The Belgian centre-forward has been widely tipped to be on his way out of Manchester United this summer after falling down the pecking order under the Norwegian manager.

Should the 26-year-old star exit the club, it would leave the 20-times English champions looking for reinforcements up front.

And former England and West Ham United boss Allardyce seems to think that former Chelsea centre-forward Diego Costa would be a great fit for the Manchester United – but only if Romelu does leave.

Speaking in an interview with talkSPORT, as cited by the Daily Express, he said: “[If I were Manchester United boss, I would not sell] Lukaku, no. Not unless I was getting Costa. I might say yes to that.”

Costa netted just two goals and created two assists in 16 La Liga matches for Atletico Madrid last campaign.

Manchester United are said to be on the lookout for a host of new signings this summer as they look to strengthen their roster ahead of Ole’s first full campaign in charge.

Thus far, they have only purchased Daniel James and Aaron Wan-Bissaka ahead of the new EPL campaign.

The Old Trafford outfit finished sixth and without a trophy in what ended up to be a disappointing season last term.

In other news, Manchester United have told Real Madrid board that they won’t consider selling Paul Pogba after the end of the British transfer market on August 8, the Mirror reports.
