Manchester United have started the season with four points out of a possible six, but they have been less successful in the transfer market.
Meanwhile, the Reds have been almost completely inactive, only purchasing Uruguayan right-back Guillermo Varela.
Fellaini has expressed his desire to move to United and join his former manager Moyes. After having their "insulting" £28 million double bid for Leighton Baines and Fellaini rejected, as per BBC Sport, it's been reported by the Daily Mirror that United will make a separate £25 million Fellaini-only bid.
Though Michael Carrick is a reliable starter for Manchester United in midfield, he lacks the aerial prowess and physicality of an ideal holding midfielder. That coupled with the retirement of Paul Scholes and the use of Phil Jones in the back line has forced Moyes' squad to play without a bruiser in the center.
The addition of the Belgian international would add that much-needed defensive presence in the midfield as well as another goal-scoring threat. Fellaini scored 11 times for Everton last season.
Ángel di María
United have had their share of problems in center midfield, but if there is one spot they really need to address it would be on the wing. Despite seemingly having the personnel to succeed on the flanks, the Reds' wingers struggled last season with injuries and inconsistency.
Even with a healthy Ashley Young back on the field, Antonio Valencia has continued his uninspiring and unoriginal brand of play, and he seems to lack the confidence to do anything other than play simple passes.
Meanwhile, Moyes has yet to give chances to Nani, Shinji Kagawa, or ex-Championship starlet Wilfried Zaha to prove themselves on the field thus far.
Perhaps that sort of chance would be given to Di María, who posted seven goals and six assists in La Liga last season for Real Madrid. The tricky-footed Argentinean would instantly fit into a United side who have only one trustworthy winger at the moment in Danny Welbeck.
Though he's been occasionally criticized for holding onto the ball for too long, his electrifying play would bring a refreshing change of pace to a band of wingers who often play conservatively.
While this acquisition is the least needed from a positional standpoint (Bale's role as a roamer isn't really something present in United's current formation, via Zonal Marking), the Spurs star would undoubtedly improve Manchester United immensely.
Whether it's his outrageous pace, ferocious shot, or dribbling, Bale's status as one of the world's elite is personified by Real Madrid's world record £86 million bid for him, as per BBC Sport.
It seemed for most of the summer that Real were unchallenged in their efforts to get Bale but it's been reported by the BBC that Tottenham have received another bid which is rumored to have come from Moyes and Manchester United.
Moyes plucking Bale from Real Madrid would devastate Los Blancos fanatics and make United firm favorites to end the season with EPL silverware.

*** Note: These transfer targets are not represented as things that could all happen, but scenarios that could happen separately. To even land one of these players, Manchester United would be fortunate, and I realize that most likely, the club will acquire only one of these players, at most. Rather than saying the club should pursue all three players right now, the purpose of the article was to name three players who United should be considering to improve their squad. ***
