Chelsea have appointed and made an agreement with Enzo Maresca. The signing of the contract will take place soon. The contract will last until 2029. One of the considerations why Chelsea chose Enzo Maresca as Pochettino's replacement was because Enzo Maresca had succeeded in promoting Leicester City back to the Premier League, after previously they had to be relegated and entered relegation. However, there is a lot of debate about whether Enzo Maresca is really able to bring Chelsea much better than Pochettino before or not. remember, it is considered that Enzo Maresca's experience is still not enough to make Chelsea better. However, that did not make Chelsea change direction, and continued to take Enzo Maresca as Chelsea's new coach until 2029.
I would like to see Leicester under the leadership of Maresca, maybe we would see Leicester repeating its path again, as it was with Ranieri. 
But it is obvious that with Chelsea Maresca will have more opportunities for a successful season than with Leicester and his choice is clear. I think that Maresca will cope with his responsibilities no worse than Pochettino, and he gets the same team, perhaps he will have the opportunity to buy several players.
