"When you get points against the top teams, you know it can make a big difference at the end of the season because it's not only three points for you, but three less for them," said the goalkeeper.
"We know we will have to defend as well as we did against PSV. I don't know if it's a good or bad time for us to be playing them, but we know in these kinds of games, it's vital we make no more mistakes."
