Twomey: The success of Chelsea’s recruitment model depends just as much on their ability to sell profitably as it does on buying intelligently. Every player who is not absolutely integral to the team Maresca is building has a price, and Madueke has never managed to make himself indispensable at Stamford Bridge.

Madueke is expected to bolster Arsenal’s options on both wings, although becoming a regular fixture on the right flank is unlikely because of Bukayo Saka’s presence, Instead, his ability to play on the left and challenge Gabriel Martinelli and Leandro Trossard for minutes is likely what’s persuaded Arteta into authorising his signing.
