• Mirror's Jack Rathborn rates Chelsea's summer transfer business
"They lost Thibaut Courtois, but replaced him by smashing the world record fee for a goalkeeper in signing Kepa Arrizabalaga for £71 million.
"They kept Eden Hazard despite his World Cup proving he is good enough for Real Madrid, whilst they added the perfect accompanying piece alongside new manager Maurizio Sarri in the form of Jorginho.
"Mateo Kovacic on loan adds another dimension to an underrated squad. Now it's down to how quickly Sarri can change the philosophy on the pitch at the club."
