"Hopefully I'll go on and have a good season,” he told BBC Sport.
"I played 15 games last season, so if I get 20-25 games it will show progress.”
He added: "He's (Cole) is one of the best left-backs in the world.
"We have a good relationship. He's more than happy for me to play more games and pushes me on."
