I agree with this. He needs to be free of defensive responsibilities too, because he does damage in the final third. I think he's probably having to compensate for a lack of overall team defending though so feels compelled to track back and "do it all". He would have been a better choice for false 9 against Brighton than Eriksen was I suspect. He does give the ball away infuriatingly often though.
100%. He's not useful in the deeper area at all. You either play him close to the goal with little to none defensive duties, or don't play him at all.
Absolutely no worries about any players that have previously demonstrated a very high quality on the pitch. These problems can be reversed with the right coaching and setup, and right now they're suffering because confidence is shot to pieces and because of the low quality of some of the players around them.
It's the players who have barely ever performed to a high standard when we have been riding high or at rock bottom that should be the concern, and there are quite a few of them.
The question we should be asking ourselves: is the setup you're talking about the right for THE TEAM or is it the right setup for THE PLAYER. It was the same under Ole, hence his purple patch, but it will be two different things when Ten Hag wants to shape his team.
He's a player who has specific strengths and can be quite dangerous under some circumstances, but I feel like he will not be a good fit for a progressive manager like ETH. With Bruno in no10 you overload opposition box and can create something out of chaos, but it has a huge burden in terms of how other players need to work defensively around him. This will not fly with Erik IMO, because this will be even more visible in possession based system which seems like another disadvantage for Bruno.
