Derby County boss Frank Lampard is convinced by the quality of Mason Mount.

Mason scored his third goal of the season as Derby earned a 2-0 win over Preston.

The on-loan Chelsea midfielder also took the corner that Richard Keogh headed in for Derby's second and Lampard delivered a glowing report after the whistle.

"He can be really good, he can be top, top level because he's 19 and plays with ability and quality, technically he's brilliant but also his work-rate shouldn't go unnoticed.

"He should never be considered a number 10 because there's so much more to his game but he'll score goals like a number 10.

"At some stage he will go back to Chelsea. I don't want to think about that now, but when he does I think he's going to be a contender."
