Thomas Tuchel has admitted that he needs to prove his worth to secure an extension to his contract at Chelsea.
The German replaced Frank Lampard at Stamford Bridge at the end of January and signed an 18-month contract with the option for the club to extend his stay.
Tuchel has enjoyed his start to life in London, leading the Blues to the semi-finals of the Champions League, an FA Cup final and they are in the race for a top-four finish in the Premier League.
Speaking to Sky Sports News, the 47-year-old said: "I had these concerns and after 15 minutes I said to myself it changes nothing how many years the contract says. I demand to deliver, to have an impact and be the best I can.
"If I deserve to stay, I want to stay as long as possible. I feel like part of the family, it is super professional, we have unbelievable support and I want to fight on the touchline with this team.
"I don't care what the contract says. If I deserve to stay longer, I will stay longer. I feel free and good, I'm at the right place. If I want to stay long, I need to deliver week in, week out."
Chelsea currently sit fifth in the Premier League with seven league games to play, and play Real Madrid in the Champions League semi-final.
