Fabio Coentrao has been linked with Manchester United.
Manchester United are set to end the January transfer window with their current squad.
Following the team's 2-0 Premier League victory against Cardiff on Tuesday night, United boss David Moyes was quoted by ITV answering a question about whether he will make any further signings:
"I would say no. I have said no, I don't think I will, but if something happens I will soon let you know."
"Manchester United have been rebuffed after making late enquiries about the availability of Porto midfielder Fernando and Real Madrid left-back Fabio Coentrao."
Moyes' disappointment at not being able to add any more faces to his current squad will have been made easier by the sight of Robin van Persie and Wayne Rooney returning to action on Tuesday.
Between van Persie, Rooney and Juan Mata, United now have an attack capable of taking them up the Premier League table and toward a place in the top four.
Although Fernando and Coentrao would have added depth, which would be handy in the run-in, neither player would have massively increased the quality of the side like the signing of Mata has.
Moyes is better off focusing on a different class of player, such as Bayern Munich midfielder Toni Kroos or Borussia Monchengladbach midfielder Patrick Herrmann, as reported by John Edwards of the Daily Mail Online.
With that being said, German football expert Jan Aage Fjortoft reports that Bayern are keen to retain Kroos:
Rummenigge in SportBild: - I hope we can get an agreement with Toni Kroos. We have to find a contract that make Toni and Bayern happy— Jan Aage Fjortoft (@JanAageFjortoft) January 29, 2014
In any case, a player like Kroos or Herrmann would have the ability to enhance the side and take it to another level.
After a disastrous Premier League campaign so far, United's lack of class has really stood out.
With Moyes aware of what positions he wants to strengthen, the club must make sure their summer transfer business is planned in advance and concluded early in order to ensure they can mount a real challenge for the title next season.
