Chelsea boss Thomas Tuchel insists no regrets selling Marc Guehi to Crystal Palace last summer.

Chelsea meet Guehi and Palace in the FA Cup semifinal on Sunday.

Tuchel said, "For Marc, it's a fantastic development and it's very hard to know if we kept him what would've happened. Maybe he needed a change, a different club, a bigger role, more minutes to develop his full potential. It just tells you over and over again that if you trust younger players, have a role for them, they can on a regular level match your expectations and even over-perform."

Tuchel was also asked about the loan of Tino Livramento to Southampton.

He added: "It's a decision we took together and we are happy with these decisions. I am happy with these decisions and it was the right thing to do given the circumstances. With Tino Livramento, we had a plan and we preferred a loan. He preferred to go and then it's better to agree to the sale."
