Where Chelsea goes next in this window feels like a mystery. After securing deals for Raheem Sterling and Kalidou Koulibaly, two established upgrades which will hopefully improve Thomas Tuchel's system, the next arrival could define the rest of the summer's business.
Will it be another centre-back? The chase for Jules Kounde might finally meet its needed end, but with the player again moving to an apparently cash-strapped Barcelona. Presnel Kimpembe, Milan Skriniar and Pau Torres have emerged again should Kounde fall through.
The alternative to a central defender could be a wing-back, given Ian Maatsen has gone on loan to Burnley and Dujon Sterling appears to be on the same path.
