What do you do when you've already got Juan Mata, Eden Hazard, Andre Schurrle, Marco Van Ginkel, Ramires, Kevin De Bruyne, Marko Marin, Victor Moses and Oscar? Oh, you sign Willian.
Just what are Chelsea doing? Why is Jose Mourinho trying to sign a player they so clearly don't need. Because if there's one area where the Chelsea squad looks like a Premier League title-winner, it's in the attacking midfield department.
Oscar, Juan Mata and Eden Hazard are all potential world class players. Kevin De Bruyne impressed on opening day, Andre Schurrle's just arrived, same with Van Ginkel.
Now, Willian is a great talent - but £32m is a lot of money. Eden Hazard money.
So if they don't need a playmaker then why try to sign one, especially for that kind of cash. Well, rumours surrounding Juan Mata's future have circulated ever since Jose Mourinho resumed stewardship at Stamford Bridge.
He's reportedly not the ideal playmaker for the 'Special One' - too slow, with and without the ball, and not the most enthusiastic defender.
Oscar played the Mata role against Hull with the Spaniard on the bench, and then again against Aston Villa with Mata on the pitch.
But where last season he played through the middle with Hazard and Oscar on the flanks, under Mourinho the Brazilian held the centre ground, with Mata and Hazard orbiting.
It's all conjecture yes, but how else do you reconcile the Mata transfer rumours, the Willian speculation and this new role?
Chelsea fans would rightly be up in arms of the Spaniard was allowed to leave.
Because he also happens to be the reigning Chelsea player of the year, the Premier League's highest assist provider, a World Cup winner.
The Blues are plainly not far off a complete squad - the bookies have them title favourites along with Manchester City.
And the reigning champions are nowhere to be seen. That's a referendum on Chelsea and City's transfer dealings, and United's lack of them.
But Chelsea's priorities lie slightly further forward. Fernando Torres hasn't looked capable of spearheading a Premier League title push since 2009, while Demba Ba never has.
Romelu Lukaku has the potential, but this season could come too soon. Because for all his goals at West Brom last season, the Belgian scored six of his 17 from the bench.
Mourinho has used him as an impact sub so far this campaign as well - and under Steve Clarke he made 35 Premier League appearances and 15 of those were from the bench.
A world-class forward should be the target - Chelsea's three top league scorers last year were Lampard, Hazard and Mata. Branislav Ivanovic was the club's fifth most prolific with five.
Edinson Cavani and Radamel Falcao may have been too expensive at £50m, but why then spend another £32m on a playmaker. It just doesn't make any sense.
They can't all play, and when players as good as these don't get on the pitch they get restless. Adding Willian to the mix risks ruining Chelsea's best attacking line-up.
And anything that risks losing Juan Mata, is a risk not worth taking.
