Chelsea manager Graham Potter says he has "no idea" of how the Blues secured the £62m signing of Ukraine winger Mykhailo Mudryk.
Mudryk had looked set to sign for Premier League rivals Arsenal before he completed the move to Stamford Bridge.
"We're delighted he is here," said Potter after the Blues' 1-0 victory over Crystal Palace on Sunday.
When asked whether he had any part in convincing Mudryk to choose Chelsea, Potter said: "I've no idea in terms of how it's happened.
"I've been focusing on the game, as you can imagine, but he's an exciting player - a player with real quality, a young player that will need time to adapt to the Premier League and to us, but we're delighted to have him.
