Mata happy Lampard inked new Chelsea deal
Mata is in no doubt his game has improved playing alongside the England veteran.
The Spanish ace, 25, told the Daily Star Sunday: "I am so happy for Frank and for his new contract - so that we can now enjoy him for at least one more season.
"For me, Frank is an example to everyone. He is like an idol for me. Lamps is a legend and, of course, now he is staying with us and is still going to be helping us.
"You can see every season he scores 15 goals or more, which for a midfielder is just unbelievable.
"And that goal of his against Aston Villa was amazing because we got Champions League qualification from it - and he got the record."
