From Arsenal we look at the two casualties of the Mikel Arteta era in Ainsley Maitland-Niles and Matteo Guendouzi.
And we explore a similar theme at Tottenham Hotspur, where Jan Vertonghen and Tanguy Ndombele have suffered at the hands of Jose Mourinho.
We also look at Andreas Christensen and Marcos Alonso struggling to make a long term impact at Chelsea, while we look at the curious case of Manchester City’s most expensive ever defender, João Cancelo.
