Chelsea manager Thomas Tuchel has revealed uncertainty over the club's ownership could be impacting contract talks with key players.
Roman Abramovich has officially put the club up for sale, but so far nobody has matched his £3BN evaluation.
Asked if the club could hold contract negotiations given the current situation, Tuchel said: Tuchel said: "Actually, I cannot answer the question, I don't know. Does it have an effect on the players? Maybe. We need to ask the players.
"On the club, I don't know. I think that we are capable and I hope that we will be capable. Right now, it is still March and we have some time but of course there are some situations that we want to have solved. We couldn't solve them.
"It is not an ideal situation. On top of it, the players do very, very well, who are concerned, I have to say. For that, credit to the players for that.
"But it shows the mentality at the club and in the building that it is also normal for them deliver despite their personal contractual situation and this is what we rely on. Of course, hopefully we will have the chance to stay in talks and solve the things how we want them to be solved for us."
