Manchester United are chasing Barcelona duo Samuel Umtiti and Sergi Roberto, according to a report in Spain.
Don Balon claim Jose Mourinho has the pair in his sights as he looks to strengthen his Old Trafford squad.
United made three signings in the summer with Nemanja Matic, Romelu Lukaku and Victor Lindelof arriving, but Lindelof has struggled to adapt to English football and Mourinho is understood to be keen on another centre-back.
Phil Jones has struggled with injury and Umtiti, 24, is the man Mourinho wants to partner Eric Bailly.
Earlier this month, Marca claimed PSG had contacted Barcelona with an exchange offer for Umtiti and former United man Angel Di Maria. The report also claimed the France international Umtiti has a €60million transfer release clause in his contract – a figure which will not deter United.
The latest report states that Roberto could be available for as little as £35million, as he also has a clause in his Camp Nou contract.
The versatile midfielder, who can also fill in at right-back, was strongly tipped to quit Barca in the summer following the arrival of Paulinho.
However, Barcelona boss Ernesto Valverde stated that he did not want Roberto to leave, telling Mundo Deportivo: “Of course, I am absolutely counting on him.
“In some games he will be a major player and in some games no, but he remains an important player.”
