The 35-year-old joined the Blues from West Ham in 2001 and has gone on to win 11 trophies during his time at Stamford Bridge, notching up 649 appearances and a club record of 211 goals.
Lampard’s future has been the subject of speculation for some time, with his current deal expiring at the end of June and Chelsea not forthcoming with a new deal.
On Monday evening Lampard, who is currently in Miami preparing for the World Cup with the England squad, confirmed what had seemingly become inevitable and thanked the club and it’s fan for the role they have played in his career.
“When I arrived at this fantastic club 13 years ago I would never have believed that I would be fortunate enough to play so many games and enjoy sharing in so much success,” he said.
“This club has become part of my life and I have so many people to thank for the opportunity. Firstly, Ken Bates, who put his neck on the line to sign me as a young player and without him I would not have even begun this experience.
“Roman Abramovich, the man who saved our Club and took us all to new levels. His desire to push the Club to the top of the football world has rubbed off on everyone.
“All the managers and coaches who have helped me develop my game during the time I have been here. I have learnt from every one of them.
“All the brilliant team mates who I have been lucky enough to train and play alongside for so long. Not just their football qualities but also the friendships I have gained along the way.
“I’d also like to give a special mention to all the staff and people behind the scenes at the club who do not receive the glory but without them the Club would simply not function.
“The club will move forward, and as a Chelsea man I have no doubt that with the quality of the players that are there, they will continue with the success that we have all enjoyed over the past seasons.
“Finally and most importantly, I would like to thank the Chelsea fans. I believe they are the greatest fans in world football. You have supported me from the moment I arrived. Not only on the pitch, but in difficult moments in my personal life off the pitch. I will never forget.
“I feel honoured to have shared so many special times with you. Bolton, Amsterdam, Munich, the list goes on and on. I, and we as a team, could not have achieved those moments without your support.
“Whatever the next challenge is for me I will always be amongst you and have Chelsea in my home and in my heart. Hopefully I will get to see you all soon to say goodbye properly. In the meantime thank you for the memories and keep making history!”
Chelsea released a statement of their own in which they paid tribute to the midfielder.
“That Lampard has won more international caps while playing for Chelsea than anyone else in our history only strengthens the argument that he is one of the very greatest players to have represented the club,” the statement said.
“Any Chelsea supporter who has had the good fortune to watch Super Frank Lampard in full flow will know we have never seen his like in our midfield before, and we will be very blessed to again see his equal.”
It is believed that Lampard’s next move will be a switch to Major League Soccer’s newest franchise, New York City FC.
