Juan Mata has urged Chelsea to hand teammate Ashley Cole a new contract.

After Cole netted Chelsea's late winner against Stoke City in their 1-0 victory, Mata was full of praise for his team-mate.

"I only realised it was Ashley after he'd scored," said the stunned Spaniard. "For a full-back it's very important to go forward as well and he showed today he is one of the best full-backs in the world."
