There are few Manchester United fans who would argue the club do not need to pick up a central midfielder this summer.
Last season, the ever-reliable Michael Carrick lacked a consistent partner in the heart of the team.
The likes of Tom Cleverley, Ryan Giggs and Phil Jones rotated in and out of the side, but none really stamped a permanent place on the position.
Part of the problem was that there was no real grit in the middle. Too often, especially early in the season, the opposition were able to waltz right through the middle of the Red Devils' lineup.
Take the 3-2 home defeat to Tottenham Hotspur for example. In that game, Gareth Bale ran riot, cutting inside unopposed to take on an exposed back line.
But perhaps it is not so much about having real muscle in the midfield.
With the exception of Carrick, there are fewer and fewer world-class midfield players in the United squad.
The towering Belgian was one of the standout players in the Premier League last term, operating in the second forward role under David Moyes.
With Moyes now at Old Trafford, it stands to reason that the Scotsman would show a genuine interest in acquiring his former soldier.
Earlier this month, Everton chairman Bill Kenwright conceded "I’ve said to David [Moyes]. We all know the situation. We all know there’s a player who’s got an escape clause" as reported by The Metro.
That player is Fellaini, who has a release clause in his contract of £23 million.
But, from United's perspective, would it be worth activating that clause?
Why He May Not be the Answer
The 25-year-old operated in the second forward role at Goodison Park last season, occupying the role filled by Tim Cahill in past campaigns.
He had his finest career year, scoring 11 league goals, but would slip back into a deeper role where he to move to United.
Fellaini may not like it, but playing as the No. 10 seems to be the role he is best at.
In the past, he was capable of great things as a box-to-box midfielder, but was never a truly great player.
He was dogged by inconsistency and a propensity for roaming out of position a little too often.
In terms of mobility, he is also not the most suitable answer. United need pace alongside the more static Carrick.
Shinji Kagawa was left to run around by himself, carrying far too much of the workload last term.
Defensively, Fellaini was solid, but as a tactical player, his ability to read the game is far removed from say, a Paul Scholes. He is just not able to control a game like the Roy Keane of old either.
If it's a dogged, tough-tackling midfielder Moyes is after, he already has Phil Jones in the ranks.
You don't need a team of Expendables to put pressure on the opposition further up the pitch and force turnovers. Barcelona and Borussia Dortmund have already proved this.
The Red Devils do not necessarily need to go after a midfield general this summer, but a man to help pull the strings and play with genuine imagination.
They need a creative threat who is able to distribute the ball to the wings and Shinji Kagawa ahead of him in the free-flowing attacking situations.
Two interesting options are Barcelona's Cesc Fabregas and Real Madrid's Luka Modric.
The former usually operates further up the pitch, but would certainly bring the marauding creativity that is needed.
The same goes for Modric, but there are significant doubts over Real's willingness to sell.
With all this being said, Fellaini would bring a lot of good to Old Trafford.
Moyes is familiar with him, he is an immense physical presence who would toughen up this side, and would provide a devastating threat in set-piece situations.
But would the manager wan't to rely on former mercenaries to strike gold at Old Trafford? Would he not want to create his own legacy with new players?
Do you think Marouane Fellaini would be a good fit at United?
