“Having worked with Misha earlier in his career, I know exactly what he can bring to our team,” said De Zerbi.
“He has the quality to change a game with his speed and ability in one-vs-one situations, and is an exciting, attacking talent.
“I will demand a lot from Misha and it is our job to help him find the best version of himself. If we do that then he can become a very important player for us. I am very happy he chose to come here, and I cannot wait to work with him again.”
Chelsea had been in talks with Leeds and rejected at least one offer for Mudryk, but Spurs entered the race at a late stage after failing in attempts to sign Iliman Ndiaye, who has since joined Manchester City from Everton, and Liverpool attacker Cody Gakpo.
Mudryk took part in Chelsea‘s pre-season tour of Australia and Asia, where he made his return in a friendly against Juventus in Hong Kong.
However, he was not included in Xabi Alonso’s squad for the Premier League victories against Fulham and Brighton, or the Carabao Cup win against Luton.
Mudryk scored 10 goals and provided 11 assists in 73 games in all competitions for Chelsea.
