Arsenal have stepped up their chase for Thomas Vermaelen’s replacement after the 28-year-old Belgian defender joined Barcelona for £15m on Saturday.
But the Gunners will have to battle United for the signing of £25m rated Borussia Dortmund centre-half Mats Hummels.
So far United have failed to agree a fee with Dortmund for the 25-year-old World Cup winner, with the German club unwilling to compromise the player’s price tag.
However, should United withdraw their interest in Hummels, they are likely to turn to 24-year-old Dutch defender Daley Blind with Ajax set to sell for around £17million.
Also, the Red Devils are hoping to seal the £25million signing of 26-year-old Columbian winger Juan Cuadrado from Fiorentina in the coming week.
