Chelsea manager, Maurizio Sarri, has avowed that his squad is "complete", following the acquisition of goalkeeper Kepa Arrizabalaga from Atletic Bilbao and the loan deal for Mateo Kovacic of Real Madrid.
The Italian also hailed the resolution of the transfer saga of Thibaut Courtois, admitting it has helped the team to concentrate fully for the new season.
Courtois joined Real Madrid in a £35m deal, which also saw Mateo Kovacic move in the opposite direction on loan.
Chelsea spent a world-record fee of £71.6million on Kepa as the Belgian's replacement, which saw him sign a seven-year deal at Stamford Bridge.
But Sarri acknowledged that the 23-year-old still has work to do if he is to live up to the standards set by Courtois.
"I'm very happy for both. The Courtois situation was clear. He wanted to go to Madrid, so we lost maybe one of the most important goalkeepers in the world now," Sarri told reporters on Friday ahead of Chelsea's Premier League opener on Saturday.
"We bought a young goalkeeper, I think one of the most important amongst the young goalkeepers in Europe. I'm really happy. I'm really happy with Kovacic. He has the characteristics for us.
"I'm really very happy and I think now the squad is complete. Kovacic is a very technical player. He's able to play between the lines of the opponent. For us it could be very important."
