Apart from the set-up that makes some offensive players not benefit from here, we can play better football with the current squad, but some essential things are missing in the squad. Ok, we have 6 points more than Forest and 10 more than Luton overall, but they play better with a worse squad.
I see us realistically on the high bottom half fully fit with the overall squad (Fulham, Palace, Wolves, Brentford). Almost all have better offensive individuals than us, but us having that defensively.
With the players you named you see the problem, our wing area. We have one of the best individual defence outside the top 7, but one of the worst in the wing/CAM area.
When I see Bournemouth, Burnley, Luton or Forest players with better ball treatment, passing skill and pace, it's something I cannot put entirely on Dyche. I'm sure we won't set up differently ever under Dyche if we get these players, but for the Everton future, we need to address this problem urgently. With or without Dyche.
The question is what players who didn't start against Burnley could have a different impact? Gomes and Garnes did a few very good opening passes, but we didn't finish these attacks and lost in the last half of the pitch due to poor touches, simple passing mistakes, pace lack, running offside etc.
Playing 4-4-2 with Beto, DCL and Patterson on the right instead of Young and Doucoure?
