Madueke joins a select group of 18 senior players to have crossed the divide and left Chelsea for bitter rivals Arsenal. Petr Cech, Kai Havertz, Jorginho and, of course, Kepa are just some of the names to have made the controversial move from west to north London in recent memory.

Finally, Arsenal fans also believe that Madueke’s arrival will block Ethan Nwaneri’s path to regular minutes. Although the England U21 international is naturally an attacking midfielder, the majority of his senior game time has come as a right winger and Madueke will likely usurp the teenager in the pecking order.

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.
