Look at today for example. Yes Doku completed some dribbles, but most times Trent funneled him to the byline or inside and Doku wasn’t really threatening for the most part. Yet the prevailing narrative is that he got destroyed by Doku.
He has actually been decent to good at defending this season yet people say he’s been a horrific defender. I don’t think this is quite true if you watch him play.
I won’t claim that he’s an amazing defender but he’s not a bad one either, he’s just a perfectly average to good defender but the narrative is that he’s a liability. It’s frustrating to see.
Southgate doesn’t have the tactical nous to understand how to use Trent at RB. Same reason Foden isn’t usually a first choice player - no idea to use him so doesn’t get the best out of him, and blames the player rather than himself. I bet most other national teams in the world would kill to have Trent and Foden.
