The Premier League champions have wrapped up two deals today.
Former Manchester City stopper Willy Cabellero has arrived at Stamford Bridge on a free transfer after his contract expired.
He will provide competition to Thibaut Courtois between the sticks, but is not expected to be their No.1 next term.
At his unveiling, he said: “I am very happy to join Chelsea, the champions of England.
“I am looking forward to meeting the guys and helping the club achieve more success in the coming season.”
And the Blues have snapped up Exeter’s wonderkid Ethan Ampadu after his youth contract expired at St James Park.
The Grecians offered him a professional contract but the Premier League champions fended off interest from a number of clubs for his signature.
He will now head to Stamford Bridge as Chelsea and Exeter thrash out compensation for the Wales youth international.
Grecians boss Paul Tisdale wished the 16-year-old well.
He said: “Everyone at Exeter City fully supports Ethan’s decision to sign for Chelsea.
“He had many options available to him and has decided that Chelsea provides him with the best opportunity to develop the next step of his career.
“We wish him the very best of luck.”
Diego Costa is closing in on a return to Atletico Madrid this summer.
That’s according to Spanish paper AS who say Atleti are prepared to buy the Brazil-born forward now and wait until January to register him.
The La Liga giants have been hit with a transfer ban and can’t register new players until Jauary 2 2018.
No fee has been agreed but Costa is said to be back in the Spanish capital, in his mind at least.
Roma star Antonio Rudiger is set for a Chelsea medical on Monday.
Gianluca Di Marzio says the Blues have now agreed a deal to sign the 24-year-old centre-back.
An official announcement is said to be expected after that.
Reports suggested Rudiger’s agent was expected in London for talks this weekend after the Blues switched their attention away from his team-mate Kostas Manolas.
Di Marzio says the Blues will pay £29m (€33m) and £4.3m (€5m) in bonuses to land the defender.
