Kepa Arrizabalaga was not the first choice of Maurizio Sarri replacing Thibaut Courtois.
The new blues boss actually wanted Atlético's Madrid star Jan Oblak as his number 1 Belgian for Real Madrid.
Chelsea went so far as to activate Offlak's £ 90m release clause in the belief that he would like to move to Stamford Bridge.
But the Slovenian goalkeeper refused the club to stay in La Liga club.
"Money speaks and I would be very worried if I were the manager of Chelsea."

It is believed that the fact that Chelsea did not qualify for the Champions League this season has played a role in his decision.
According to The Times, Atletico Oblak rewarded with a wage boost because he had rejected the chance to join the Premier League.
Chelsea could still sell the stars Willian and Eden Hazard this summer, reports Sky Sports expert Matt Le Tissier.
"I do not think you can take it for granted (that they will stay)," he said of Willian, who was also associated with Real and rivals Barcelona and Hazard.
"The opportunity is there and when someone comes in, a Barcelona comes back for £ 90 million or so, Will you refuse?
"As a business you can refuse it? That's a lot of money."
Chelsea boss Sarri could still lose three key players, according to Paul Merson.
"As you said about Hazard and Willian, I'd put ridge in," Merson said.
"Who would not want him when PSG or someone comes in and goes" oh, 100m ".
"The season tickets are now sold, the bottom is sold out.
"Chelsea does not have to worry about selling seats.
"The money speaks and I would be very worried if I was currently the coach of Chelsea just because they have three big big players there who could easily play for Barcelona or Real Madrid every day."
