Rio Ferdinand believes Manchester United need to sign two centre-backs in Marquinhos from PSG and Ronald Araujo from Barcelona to help improve their side ahead of next season.
United have endured a disappointing campaign, with hopes of even landing a top-four place looking bleak despite defeating Tottenham Hotspur 3-2 at the weekend.
However, the win over their top four rivals featured glaring errors at the back including an own goal from skipper Harry Maguire.

United had signed Raphael Varane from Paris Saint-Germain over the summer to try and strengthen their back four, but Ferdinand claims the Red Devils will need to raid the French giants again for their captain Marquinhos as well as land Ronald Araujo from Barcelona to boost their back line.
