As the dust settles on a fifth home defeat for David Moyes and Manchester United, attentions turn back to the club's pursuit of January transfer targets.
Coentrao has only featured a couple of times for Carlo Ancelotti's team this season and has been told he can leave the Spanish giants ahead of this summer's World Cup finals in Brazil, per Mullock's article.
The Mirror also reports that the Portugal left-back will be made available at around the £12 million mark.
Coentrao was a deadline-day loan target in the previous window for Moyes, only for the deal to collapse at the eleventh hour, due to a paperwork issue.
Ancelotti said at the time, per Sky Sports: "Fabio is staying. I understood that he wanted to go, but really it was not the same desire for everyone. Now he's decided to stay and everybody, the club, players and coaching staff, are happy with this decision."
The 25-year-old defender would add much-needed quality to Moyes' failing squad. His versatility would also be an asset to United with his ability to play on the left wing and as a defensive midfielder.
For a player that cost Madrid €30 million in 2011 from Benfica, the transfer would represent real value to United, as the rebuilding process after the departure of Sir Alex Ferguson begins in earnest.
With Patrice Evra's contract about to expire, and the lack of quality from squad alternatives like Alexander Buttner and Fabio, the left-back position is a priority for Moyes.
Coentrao is the type of player Moyes truly needs. He is an individual who knows what it is like to play at the highest level of club football, with more international caps than his positional counterpart Baines.
Should Manchester United sign Fabio Coentrao over Leighton Baines?
Coentrao ticks all of the boxes.
Moyes will be desperate to freshen up his options, as United lie 11 points behind Premier League leaders Arsenal.
