How successful do you expect Enzo Maresca to be?

I expect maresca to be quite successful. Though he has no strong background as a coach, but pep's blue print may help him to rebuild the club. Maresca can guide Chelsea in the right direction. But, Todd Boehly must be patient for Maresca to deliver. Maresca will struggle on his first season. He's building Chelsea from scratch. Then, he will do better in his second season. But, it will be amazing if maresca can speed up his development to his club. It would be great if Maresca can follow how Real Madrid develops their talents. But the problem is, Chelsea lacks many good veterans in the squad to shorten the time in developing their young talents.
I was very disappointed when chelsea sold a lot of veteran players, but yeah, we must move on. Chelsea is now having maresca as a head coach, which will also responsible for developing the young talents. And for the last, I hope Maresca will not face many obstacles. He needs to develop young talents to play better, and bring back Chelsea's winning mentality.
Enzo Maresca needs time and full support from club management and the players to improve Chelsea performance again to become a team to be reckoned with in the EPL. His experience when he was Pep Guardiola assistant and led Leicester City to win the Championship attracted Chelsea to hire him as Pochettino successor. After the Chelsea coaching chair was occupied by Enzo Maresca, So adding to the competition between students and teachers in the EPL, Guardiola will be challenged by students such as Arteta, Enzo Maresca and Ten Hag in the competition for the championship. A good response from Chelsea management will make it easier for Enzo Maresca to rebuild the Chelsea squad which had slumped during the Tuchel and Pochettino era. New players are starting to be brought in to build a new project after going through a critical period in the last few seasons.
Senior players are really needed in the squad to lead younger players. Team cohesion will be tight when the squad is led by senior players. They must learn from what Jose Mourinho did, who built the Chelsea squad with players from different generations. John Terry, Lampard and several other senior players were retained to maintain squad balance. Maresca must adopt this philosophy to achieve maximum results as expected by club management.
