Looking at the players leaving Chelsea, I think the team needs to do something to get stronger. To be honest they make a lot of money but they don't transfer new players to replace the players who left the team, they can't be successful that way
Most of the players that left Chelsea really worth leaving, most of them are of no use to the club, they are not making any positive impact on the clubs performance, so is just better as Pochettino allows all of them to leave, and Pochettino signed some players which am sure they are going to perform well in Chelsea. Pochettino is trying to build a new squad in Chelsea which i believe that's what Chelsea really needs now, and am happy with the way Pochettino dispose those players.
Teams like Liverpool, Manchester United, and Chelsea did not perform as well as expected last season. And so before the start of this season, they have to make some important changes within the squad.
Seriously Manchester united performance wasn't bad last season compare to Chelsea performance, at least Manchester united ended the season in top 3 not like Chelsea, and Manchester united coach is trying to fix the errors that happened last season, Manchester united are even trying to get a new goal keeper because their goal keeper performance dropped at the end of last season.
From this, it can be assumed that the Premier League will be more crowded in the next season. A number of teams will be fighting for the title, as well as a number of teams fighting for Champions League qualification.
Next season will be very competitive because most clubs have spent reasonable amounts of money on players which i believe its really going to help them, no club should be underestimated next season, even the clubs that didn't perform well last season are going to perform well next season.
