Tottenham goalkeeper Michel Vorm is up for his chance tomorrow against Burnley.
With Hugo Lloris injured, the Dutch stopper is set to take up duties between the sticks on Sunday.
"We're quite an attacking team but a 'nil' at the other end of the scoreline is very important, especially if you want to win games," he told the Spurs website.
"A clean sheet is something that's very important to a goalkeeper and the defence but you're not only defending with the back four, you need to do it with the whole team and that's something that we need to be sharp on.
"We know that we have to be focused for 90-plus minutes against a team like Burnley, as they are going to give their all and could be a threat from set pieces or on the counter-attack."
