5 players Manchester United should sign this summer

#1 Antoine Griezmann:

Griezmann was close to joining Manchester United last summer

Griezmann was close to signing for United in the summer before Atletico Madrid were hit hard by a transfer ban from FIFA. Hence, the Frenchman chose to stay in the Spanish capital and sign a new contract under condition that his transfer fee would remain unchanged after this season.

Mourinho's team lacks the kind of flair and attacking instinct that Griezmann brings to the field. The French international is capable of playing as a secondary-striker or as an attacking-midfielder. Such versatility would be of tremendous use to Mourinho who has shuffled between a 3-5-2 and 4-4-2 formation this season.

The Frenchman is reportedly on Barcelona's radar too, but the deal could be off after the signing of Philippe Coutinho from Liverpool. Manchester United need to sign stars of Antoine Griezmann's quality to challenge giants like City and should be doing everything in their power to ensure he ends up in Manchester next summer.
