Sunderland goalkeeper Simon Mignolet says one season isn't enough to prove he's Premier League class.

The Belgian is staying grounded after an outstanding campaign.

"It's way too early for me to say that I have shown people in England that I'm a top goalkeeper," said Mignolet.

"I learn new things in every game and in every day's training.

"Since I arrived at the club, I played the majority of games and as a goalkeeper that's what you want to do. I am going to work hard in pre-season once again and show the gaffer that I am ready to play again."
