|9/4||Chelsea are 9/4 with Bet365 to win the Premier League|
Lampard is the all-time leading scorer for Chelsea - with 211 goals - and the two Spain internationals, who have played alongside the vice-captain for a combined five-and-a-half years, hailed his impact on the game.
"Good luck Frank, and thanks for everything. I wish you the best in whatever you do in football and outside in the future! #Lampard #Respect," Mata wrote on Twitter.
Torres added on Instagram: "Thank you for everything Lamps. Top professional, top man, top player. It's been an honour play alongside you. #chelsealegend #respect."
Lampard is rumoured to be close to joining new Major League Soccer team New York City FC, who signed David Villa on Monday, with a number of other clubs reportedly keen on the England international's services.
