Chelsea is already back become a team that can't be underestimated, even though they're currently at 11th rank, but sooner or later they will climb up if they performance are same like now. Shout out to Mudryk since he's the reason why Chelsea win in this match and also Palmer, Pochettino wasn't wrong to spent 44 Million Euros to buy him. I think if both Palmer and Gallagher play in attacking midfield positions, just like Manchester City's strategy, they will be stronger.
In as much as I wouldn't want to sound like underestimating Chelsea, I also wouldn't want to see them as they can really do much because they are not even looking like they can so I will rather just accept them as they are and see them within their performance and see to it that that's how well they can perform this season and hope they be improved by next season enough to do much better than they did this season.
If palmer plays in the attacking midfield position like you have suggested with similarities to Manchester city strategy I don't think bit will be a perfect idea because Chelsea don't seem to have that strength that will balance the midfield using such tactical approach, it will be better he maintains his position and pochettino finds a better approach with which he will position his plyers to get the desired results the hope to achieve from the team, strengthen their midfield is another thing they should put to consideration probably by next season.
Chelsea can still return to their glory days but not in this season and they will have to fix their midfield and a little touch around their defense to be able bro achieve that, they have got a fair attacking line which needs some brushing and they will be much better, overall Chelsea doesn't seem to have a bad squad but have a poor tactical approach to their games and that's what pochenttino should work on.
