The big thing for me was :
i) Bradley getting injured and Trent coming back into the team (not blaming Trent, just the effect it had on our tactics);
ii) coinciding with Trent being back in Jurgen changed the shape and patterns of the whole team; our forwards have taken a lot of s*** but their positions and what they were asked to do changed from game to game, particularly Nunez and Gakpo.
I don't 'blame' Jurgen as such - he's knackered and deserves nothing but our support and appreciation. With no evidence whatsoever I going to say he's let Ljinders have too much say over tactics for the last couple of months. Never go full Ljinders in the middle of a season.
