West Ham United youth chief Tony Carr says Frank Lampard's dedication has helped him achieve success at Chelsea.
Lampard came through as a junior at West Ham under Carr.
"I use Frank as an example to the boys I coach today," Carr told the Mail on Sunday.
"Young Frank - I still refer to him as that because his dad will always be Big Frank -would come into training on his days off. He would put cones out to mark the two penalty areas. He'd sprint from one box to another, jog back and sprint again. That's how he got the fitness to go with the technical ability he had. A great example for any player."
