The Argentine centre-back has had a terrific season on loan at Atalanta from Juventus and now makes up a three-man shortlist of targets for the Red Devils.
According to Sky Sports, United have made signing a new centre-back their summer priority and Romero fits the bill, given his age and ability.
The report goes on to claim that Lille’s Sven Botman and Sevilla defender Jules Kounde are also on United’s wishlist but it is Romero who is their main target.
Following a superb season under Gian Piero Gasperini at the Gewiss Stadium, Atalanta are expected to pay their obligation to buy fee of £21.5million (€25m) to make his move permanent but would then be open to selling him on for a higher fee.
Sky Sports report that Atalanta would be open to selling Romero on for a fee in the region of £34m (€40m) if clubs showed interest in the player.
United could be one of those clubs to do so, with Ole Gunnar Solskjaer now turning his attention to improving his defence and midfield after Edinson Cavani extended his United deal by another year earlier this week.
With Cavani staying put, a move for a centre-forward is reportedly highly unlikely, which will see United wait another year despite being linked with Harry Kane and Erling Haaland.
United legend Rio Ferdinand believes strengthening the backline is imperative, given how impressive his former side can be going forward.
‘I think Manchester United’s prime position for them to strengthen, to really improve and become a team who can compete is centre-back,’ Ferdinand told BT Sport after the 2-1 defeat to Leicester on Tuesday.
‘To get a partner for Harry Maguire who you go, actually every week he produces, he’s there.
‘At the moment there’s too many players centre-forwards especially who probably are looking when they get in the tunnel and are thinking, “I’ve got a chance here. I think I can smell a chance.’
Romero has made 39 appearances for Atalanta in all competitions this season, scoring three goals and creating five more, which has left the club in second in Serie A.
Manchester United ready to Sancho fee.
Manchester United are consistently linked with Borussia Dortmund star Jadon Sancho even though the there is still a lot of time for the summer transfer window to open.
The Red Devils failed to lure him last year, so, perhaps they are acting early to get his signing done this time around.
On 7th May, Sky Sports revealed that the German Bundesliga side demanded a fee worth £108million last summer but could let their attacker leave this year for just £80million.
Two days later, Bild covered a story and stated that the 21-year-old winger wants to move to England and BvB will not come in his way. However, it was reported that he would only be sold for a minimum price of 100 million euros.
More recently, the German source have covered another article which is very positive for the Old Trafford outfit.
Bild claim that Man Utd are ready to pay 90 million euros (£77million) to agree the fee for Jadon Sancho and it is claimed that the offer could work to finally hire the services of the England internatinal.
