Chelsea are a team without a right side.
The release of Salomon Kalou and Jose Bosingwa over the summer left Roberto Di Matteo's side with no specialist right sided first teamers.
The incumbent right back, Branislav Ivanovic is a converted centre back and his backup Paulo Ferreira is no longer of first team quality.
In midfield, backup squad player Yossi Benayoun is more of an advanced central player and Ramires is a central all-rounder. Daniel Sturridge is a striker who presents another potential solution, but none of these options possess the ability to trouble the Premier League's best.
So it was curious watching Di Matteo recuit a plethora of advanced central or left sided players of first team standard over the summer. In came Marko Marin, Oscar and Eden Hazard to compete for a starting place with the pre-existing Juan Mata, Ryan Bertrand and Florent Malouda.
Surely amongst all of this transfer activity Di Matteo could have found the time to buy a decent right back and a world class right sided attacking player? Apparently not.
Against Wigan, Di Matteo's solution to this imbalance was fluid; with Hazard and Mata interchanging between advanced right and central positions until Hazard was replaced by Oscar on 64 minutes.
Mata couldn't be considered a permanent right sided option due to his complete inability to defend. Stronger teams than Wigan will waltz straight through him, so his selection in this position against Wigan is surely temporary.
It was curious, considering the other options available, to see the anonymous Bertrand deployed on the left side of midfield. Surely the intention wasn't to pay close attention to Wigan's right sided Emerson Boyce, a lumbering converted centre back.
Despite the number of attacking midfield options that Chelsea have available, I doubt that their transfer activity is over for the summer and it would makes sense for owner Roman Abramovic to pull out the petty cash tin for a player like Porto's Hulk.
