It's no secret that the current Arsenal side need only one or two additions in key places to complete their transformation from perennial fourth-placers to genuine title favourites.
The defence could do with one or two additions and Wojciech Szczesny needs some competition, but ultimately the thing they need more than anything else is a powerful goal-scorer.
Olivier Giroud has so far excelled this campaign, and will be hoping to finish the season with the label of a 20-goal-a-season striker. However if he doesn't happen to be firing on all cylinders, his list of direct replacements makes for pretty poor reading.
Various targets have been linked with the Emirates, in particular current Madrid whipping-boy Karim Benzema, but in my opinion Arsenal need not look any further than one of their most prominent rivals for a man who could do the most damage.
Enter Romelu Lukaku.
The Belgian starlet was scintillating for West Brom last term, but rather than being offered his chance to pin down a first team at Chelsea, he was once again shipped out on loan.
Obviously Mourinho intends to allow Lukaku time to develop away from the pressure of Stamford Bridge, and I'm not naive enough to think that Chelsea would be the least bit open to the idea of selling him, but there may be a chance if Arsene Wenger can place an offer that's too lucrative to refuse.
When it comes to strikers Jose Mourinho likes to work with a finished product: fact.
During his first reign at Chelsea he bought one Didier Drogba, fresh from a ground-breaking season in Ligue 1 and the-then UEFA Cup.
At Inter he moved for the distinguished Samuel Eto'o, who had already cut his teeth at the Nou Camp and proved he was capable of doing the business at the very highest level. Even at Madrid the Special One opted for seasoned world-class players rather than emphasising the development of youth.
Wenger on the other hand is a master at nurturing young talent in a way that ultimately realises the highest potential. If he could get his hands on Lukaku then there's no telling how complete the forward could become.
In reality I think Mourinho wouldn't be too distressed at the thought of losing Lukaku if he could get his hands on a striker of his choice to remedy the current goalscoring predicament at Stamford Bridge.
Samuel Eto'o, Fernando Torres and Demba Ba could all be shipped at the end of the season unless they start finding the net prolifically, and don't be surprised to see Mourinho opt for a radical overhaul of his frontline rather than entrusting the returning Lukaku to do the job.
Lukaku himself would surely be willing to move across London if he was guaranteed a starting berth at Arsenal, something that may yet elude him still at Chelsea if he returns from his loan at Everton to find increased competition.
It's an unlikely proposition at best, completely unrealistic at worst, but I think Wenger could really ruffle some feathers with a declaration of interest in the young Belgian.
Lukaku is powerful, athletic and good at bringing team-mates into play, and under Wenger's tutelage he could become something very special indeed.
Mourinho on the other hand could quite easily dispense with the 20-year-old if a big name striker comes onto the market, and may well be convinced to sell if a combination of Lukaku being deemed surplus to requirements and Wenger launching a substantial bid comes to fruition.
