"I think I am probably in the best form of my career, although I will leave that up to other people to decide," said Williams.
"It is always nice to hear people say nice things about you and a lot of people have been talking and saying good things.
"So it just means I'm probably doing my job right and I try to keep working hard.
"But I don't think that I am the best in the Premier League or anything like that. It's just about keeping at my game, going again and playing well at Wembley."
