5 players that Manchester United should sign in the upcoming summer transfer window

#4 Toby Alderweireld

The Belgian would add the much-needed defensive boost to the squad

Manchester United need quality players at the back and they are also short on replacements as Phil Jones, Marcos Rojo and Eric Bailly have a tendency to get injured every now and then. The Red Devils have been interested in Alderweireld for quite some time now and this summer, they need to sign the Belgian.

Alderwiereld can alter the look of United's backline and his experience in the Premier League will benefit those who play around him. With his €25 million release clause, the Belgian is available for a cut price deal and someone of his quality should be snatched up by the Red Devils.

#3 Alex Grimaldo

Grimaldo has been impressive this season

Manchester United need a backup left-back to Luke Shaw as they don't clearly have one. Diogo Dalot or Ashley Young fill in for Shaw in his absence and both of them prefer to play at right-back. Alex Grimaldo can be a perfect backup to Shaw.

Grimaldo has been playing consistently well for Benfica and the 23-year-old Spaniard can really push Shaw to be better. Grimaldo is an attacking full back by nature and his brilliant movement in the final third can cause any defense problems. Still very young, Grimaldo can prove to be another astute signing by the Red Devils.
