Chelsea boss Thomas Tuchel said "whoever buys the club will be lucky to have it", and added his commitment to staying with the Blues.
He has taken the decision following his country's invasion of Ukraine.
"Chelsea, for me, is a perfect fit. I love to be here and love everything about the club and, hopefully, it continues," said Tuchel.
"There is now uncertainty but isn't there always as a football manager?
"I'm used and trained to live with it. Of course, different levels and, I have to be honest, this is quite a level but I am positive and hope things will end well.
