AS Roma whizkid Erik Lamela is convinced of a big season ahead under new coach Zdenek Zeman.

Lamela has caught the eye on Roma's preseason tour of the US.

"We work really hard with Zeman. I'd never experienced anything like it before, but I am sure it will pay off. Roma will improve on last year's results," he told the Corriere dello Sport.

"The tactics represent a completely new way of staying on the field for me. At River Plate I was accustomed to waiting for the ball in every move, so it all went through my feet. At Roma it is very different."
