Guardiola is a master in rotating players and his strategies and tactics makes it even easier to do so. My eyes are on Chelsea next season, they are one of the teams to look out for. With Pochettino taking as manager, I would want to see how well he can utilize the players at his disposal and what tactics and formations he will be working with to get the results. I really hope they will not repeat the poor form of the just concluded season.
Not only Chelsea, Manchester United should also be considered. Manchester United is a team that has been pretty solid under Ten Hag, so you shouldn't ignore them either. I also know Chelsea are looking for a way to be in better shape, but Pochettino needs big time and support.
Chelsea could still fail if Pochettino's strategy and plans don't pan out in the first season, but they are a team looking to move forward. Apart from that, Liverpool will also try to show their class and Arsenal also look very dangerous.
