Chelsea defender Kurt Zouma says he won't be ready when next season's campaign kicks off in August.
The 21-year-old suffered an injury to his anterior cruciate ligament in February and is still recovering to regain full fitness.
He admits that his future at the club is uncertain after the appointment of manager Antonio Conte but also that he is ready to work extremely hard to secure a regular place in the Italian's line-up.
"I am working hard every day, from 10am to 4pm I am working on the knee and on some cardio," Zouma told the Telegraph.
"I won't be ready for the start of the season, but the doctor is happy with my knee and I'm feeling good. I have to take care and not rush, so I will take my time.
"Of course I am watching the Euros. I'm a France supporter and I'll watch every game. It's an important competition and we want to win it. We have the squad to do it. Unfortunately, I cannot get back to France to see any games live because of my rehabilitation.
"I am not worried about the new manager coming in.
"I did well before I was injured. I will speak with Conte and see what he wants from me.
"The new manager wants to do much better than last season and he will bring in new players. That is not a problem. When you are at a big club like Chelsea there is always big competition for places.
"I was happy with myself and I did well when I was playing. Now I have to be ready for next year. I am very happy at Chelsea and I want to show everyone that I will be back even stronger after my injury."
