Sweden international Andreas Granqvist has confirmed that Manchester United are interested in signing him during the January transfer window.
Mourinho has regularly hinted that he is unhappy with the defensive options at his disposal so far this season, having failed in his attempts to bring a new centre-back to the club during the summer.
Helsingborg defender Granqvist has emerged as a surprise transfer target for the Red Devils, and the 33-year-old revealed that he would be interested in moving to Old Trafford should United make their interest concrete.
"There is indeed interest. I am honoured that I am linked with such a big club," Granqvist told Expressen.
"If there is a concrete offer in January, then both the club and I will accept that, but that is currently not the case."
Granqvist, who has previous experience of the Premier League following a short stint at Wigan Athletic earlier in his career, would be expected to join United on loan until the end of the season.
