If there was a semi-available, semi-famous player out there or someone who was linked with a transfer to another big club, Chelsea tried to sign him. And despite spending €630 million on transfer fees across both windows, the team finished in the bottom half of the Premier League table. And then came last summer, when Chelsea signed a ton of youngish players with top-league experience. They could start redirecting the billion-plus in transfer fees on a couple more stars to complement Caicedo and Palmer. Why none of Chelsea's new signings move the needleIn a vacuum, almost everything Chelsea have done so far this summer is defensible.
