Manchester United are looking for Harry Maguire’s long-term partner, with doubts left about Eric Bailly and Victor Lindelof.
According to La Gazzetta Dello Sport, Romero is being targeted by United after playing on loan at Atalanta BC.
Romero was one of the leading defenders in Serie A last season, helping his team get 7 clean sheets on their way to 3rd place.
Atalanta have a chance to buy Argentina overseas for £ 21.5million, which they now look like they will do.
However, Manchester United are said to be testing La Dea’s decision by making a $ 39m bid for the 23-year-old.
Man United finished 2nd in the Premier League last year and are said to be looking for four new players this summer.
