The Argentina international penned a five-year deal with the Red Devils on Tuesday evening after United agreed a club-record £59.7m deal with Real Madrid.
Why don’t they go and pay £35million for Hummels first? We know Dortmund, as good a side as they are, are a selling club
Louis van Gaal’s side have already conceded a staggering seven goals in three games in all competitions, highlighting a need to strengthen their defence.
And former United captain Wilkins criticised the Red Devils’s transfer policy this summer, stressing that Van Gaal needed to sign Hummels and Khedira.
“They are putting the roof on before the foundations of the house,” Wilkins told talkSPORT.
“I think they spent the £60million unwisely on Di Maria.
“Why don’t they go and pay £35million for Hummels first? We know Dortmund, as good a side as they are, are a selling club. Take him out of Dortmund and put him in alongside Phil Jones.
“Then go and get Khedira for £25million. There’s your £60million and you already look more solid.”
