The comparisons to Dele Ali are lazy imo. One's been out of shape/down the pecking order at his club and the other has been addicted to medication dealing with mental health issues.
If Philips could stay fit then Dyche is the type of manager to sort him out !
Phillips has kind of a strange career. Never a youth international and "just a Championship player" until he met Bielsa as a 23 year old. Bielsa started playing him more defensively, often as a central defender, and Phillips developed rapidly. Beaming with confidence for a high-flying Leeds team and the development during Bielsa's guidance made him an England player.
Nothing before he was coached by Bielsa made people think he was a future England player. Nothing he has done since playing for Bielsa has made him look like an England player. He was a player that during a spell, playing for a certain manager, looked great. That doesn't make him a great footballer.
Ancelotti coached an Everton team that would dominate Dyche's Everton. With Mason Holgate as arguably the team's best player. DCL and Godfrey were both full internationals while being coached by Ancelotti. Shame Dyche isn't "the type of manager to sort them out".
Not sure what players Dyche have sorted out. Ever. Goalkeepers and defenders often look good playing for him, but can anyone name a midfielder that has looked better playing for Dyche than other clubs? Garner and Onana both looked worse after Dyche came in. It feels like it is a matter of time before any promise Iroegbunam shows will be coached away. Gueye has looked decent, but he will always look better playing for teams that doesn't want to have the ball.
Some might argue that Doucoure has improved playing for Dyche. He has always been a liability with the ball. Rule of thumb should be to not let him have the ball in the defensive half. Meaning benched (by Lampard) or to play him more offensive and not to try to play through the midfield (Dyche).
Playing as a central midfielder in a Dyche team means that you in most matches will be outnumbered 2v3 or 2v4. Even the most talented midfielders would struggle to shine when that is the case. A well coached team could and should play through Everton's midfield blindfolded. We could play Rodri and Rice in the midfield and still be dominated. That is the reality. And it is by design.
It is a hell of a lot easier to look decent as a midfielder for City or West Ham.
