Sir Alex considering Kjaer swoop
13th-placed Palermo may now struggle to hold on to their prize asset, believed to have an £11 million release clause in his contract.
And Kjaer revealed earlier in the summer that he would not think twice about the possibility of joining the Red Devils, despite being a Liverpool fan.
“If United just had two defenders whilst Liverpool had three I would choose United without hesitation," he said.
“It does not help to choose with the heart in that kind of situation. I am a professional."
However, former Middlesbrough striker Mikkel Beck - now Kjaer's agent - has admitted that Sir Alex may have to wait until the summer to sign the 20-year-old.
“A clause in his contract will allow him to move during a set period in the summer,” he said.
