However, while Rooney is a piece that perfectly fits Jose Mourinho's puzzle, the question must also be asked in reverse, as to whether or not Chelsea is the right fit for the Red Devil.
Sky Sports recently reported that Mourinho was unwilling to comment on speculation that his side are reviving interest in a player with whom they were strongly linked over the summer, giving no new information on the potential blockbuster move.
However, while all the financial details and squad requirements may appear to go in Chelsea's favour, all may be for nought if Rooney's desire isn't the same at Stamford Bridge.
Sky Sports quote Mourinho as saying:
I don't want to speak about it. We play Man United in a few days. I don't think it's nice to speak about a Man United player.
You have to ask him (Rooney). You have to ask the player. And Man United because Man United has a contract with the player that doesn't end at the end of the season.
As things stand, Rooney's deal with Manchester United runs until the summer of 2015, and if a new deal isn't agreed over the next six months, a daunting 2014-15 campaign lies ahead, with the chance of United losing their superstar for nothing at its close.
Where would Rooney win more trophies?
One significant trademark about Rooney's play is his passion. Passion on the ball and off of it, there's not much that the forward doesn't devote 100 percent toward.
Love him or hate him for it, David Moyes' club are the ones who have earned the most out of that desire to win, building a bond over the last 10 years, the likes of which is becoming increasingly uncommon.
Back in October, The Guardian's Daniel Taylor reported that the speculation linking the player with a move over the summer was due to him being played out of position:

At 28 years old, Rooney is in his playing prime and could even go on to better things were he to move to west London, but there's no guaranteeing the same spirit would be around.
Of course Rooney wants to win trophies and play at the very peak of his abilities, but a sour aftertaste would permeate from any Old Trafford departure, making Chelsea's potential purchase that much less valuable.
While he'd be the same, ferocious attacking threat physically, there's a whole other side to Rooney in terms of his mental state, and there's no guaranteeing Chelsea would be able to preserve it.
