Carrasco, the former Atletico Madrid winger, is reportedly keen on a return to Europe with United, Arsenal and Milan keeping tabs on him.
Carrasco, 25, left Atletico to join Chinese club Dalian Yifang last February.
His wife, Noemie Happart, told Belgian outlet RTBF Sport: “They [Manchester United] are very interested.
“I do not hide it but nothing is signed. Yannick and his club leave tomorrow in preparation in Spain.
“Yannick feels good in China but it’s a very different culture, it’s far from our families and our friends.

“But it is true that when we heard that some clubs were interested in Yannick, it interested us too.
“Now, we will see how it will happen, how things will unfold and who knows, we can go back in Europe.”
Carrasco has scored seven goals in 25 appearances for Dalian Yifang since moving to the Chinese Super League last February.
He and former Atletico team-mate Nicolas Gaitan moved to Dalian Yifang on the same date, but they failed to perform well enough to guide the club any higher than 11th in the 2018 CSL season.
