Wayne Rooney is an extraordinary striker.
Year after year, putting all controversies aside, the 28-year-old produces for Manchester United.
And this season, Rooney has been at it again, scoring eight times in the Premier League and, even more impressively, creating five assists - the third-highest total in the division.
It is this ability to contribute to the team that has always made Rooney stand out from the crowd.
At the same time, it might just be the main factor attracting interest from Chelsea boss Jose Mourinho.
The Portuguese coach has always been a fan of hard-working, dynamic players. Just look at Juan Mata earlier in the season, when he was dropped from the Blues' first team for a lack of work-rate and tracking back.
Yet it is this aspect of Rooney's ensemble that would also ensure that a move from Old Trafford to Stamford Bridge would be far from ideal for both parties.
Rooney is, in essence, an all-round number 10. The England forward drops deep to collect the ball, makes key passes at key times and even takes corners and free kicks.
Yes - because that is the exact job description of the likes of Oscar, Mata, Andre Schurrle and Eden Hazard.
Chesea already have their own dynamic, deep-lying forwards to mould into a squad. Adding Rooney would just complicate things even further.
What Blues fans are endlessly calling for is a clinical number nine. A Falcao.
Even then, Mourinho has at his disposal the likes of Fernando Torres, Samuel Eto'o and Demba Ba - no matter how much they have underachieved up to now.
Bringing Rooney in to play as a lone striker would not solve the dilemma but simply increase the probability of it occurring.
Indeed, if the 28-year-old led the line for Chelsea, he would become more of a false nine, dropping deep and blending in with the Blues' attacking midfield.
If Mourinho wanted that, he could just play Mata, Schurrle or Hazard up top.
Why, then, would it make any sense at all to spend £30 million plus on a new way of causing the same old problem?
Would Wayne Rooney be a bad signing for Chelsea?
