Chelsea's ambition to cut down on their squad size by ridding themselves of too many fluid players that are neither here nor there in attack has started. Joao Felix's loan was the end of his time in west London and Kai Havertz's true best position is still unknown.
The general consensus is that Mikel Arteta will make him a midfielder that drives from deep. Anyone that watched him at Stamford Bridge under Frank Lampard would be justified in questioning the reason behind such a shift.
Christopher Nkunku, though, has arrived and is the archetypal Chelsea signing of the past five years. He is a player without a defined position and that would ideally like to play behind or in support of a true focal point in attack. The issue presented to Blues bosses over the years has been the distinct lack of success when it comes to trying or judging their strikers.
