Mauricio Pochettino is proud to be taking charge of Chelsea.
The Argentine enjoyed a first day on the job on Monday.
"In the last 10, 12, 15 years, Chelsea is the greatest team in England," former Southampton and Tottenham Hotspur boss Pochettino said.
"I know very well the Premier League and what the culture of Chelsea means. I think our fans are excited to again be on the road of trying to win.
"We are excited to work with a very young team, with a different approach than in the past.
"But I think we all need to understand that we have to work really hard and create a very good atmosphere at the training ground to build success for the team in the next few years.
"For me, it is a pleasure and honour to now be involved with Chelsea Football Club. We are so excited, and I know Chelsea very well, it is one of the greatest clubs in the world. So of course, it was easy for us to make the decision to move here."
