Todd can indeed buy players at expensive prices but sometimes the players are not as expected. Moreover, Chelsea doesn't need to buy expensive players but quality and productivity are highly sought after. It doesn't need to be expensive as long as the player is productive enough that is good enough, but I'm sure in the end if Maresca If it fails, of course the fate will be the same as Pochettino's because Chelsea can't wait and go through the process. What they want is for Chelsea to achieve the target, I don't know the vision and mission of Chelsea and Maresca, what agreement they are targeting, whether winning the EPL or other competitions. but the adaptation of the players and Maresca seems to be affecting the start of the new season.
Players sometimes isn't really about the money, they revolved around luck too. The best time to sign a player is when they have not been recognized, just small fame and performance within the club is okay for the sighing, this is what I see big clubs like Manchester City, Real Madrid and Bayern Munich do most of the time and then after they make use of the player and build hype around him, the likes of Haaland, Jude Bellingham are real example of fame after getting to big club, this is what Chelsea need to do.
There are some clubs that are uniquely based on building players, they go to other small divisions and but players at cheaper rate, build them with a small hype and then sell at average price to bigger clubs, Chelsea can reach out to those clubs and make good deals for the development of the club, there is no point in wasting money buying expensive players that wouldn't add anything meaningful to the club.
I can remember one coach who has adopted this strategy so well. Arsene Wenger of Arsenal back then used to sign academic player from the age of 16 and bring them to Arsenal. He begins to train them without playing them in the EPL yet. After sometimes he sells most of the players in the league and brings the young players to shine after they have shone, he sells them and brings other young players he has been preparing. These strategies only help in bringing money to the club and not trophies. Chelsea needs players to win trophies not money yet to the team. This is because they have the money all they want is the qualified players to win trophies for the club.
I still insist that scouting for players shouldn't be about hype and praise. There are lots of players in other leagues that are not well known. If you go there, you will see young and talented players that will deliver in the EPL still. Declan Rice was bought for 30 million Euros, look at his performances in his debut season in Arsenal and how his market value has increased significantly.
