Tottenham Hotspur goalkeeper Michel Vorm has described the team's League Cup semi-final second leg at Sheffield United as their "biggest game of the season".

Spurs take on the Blades at Bramall Lane tonight, having earned a 1-0 win over the League One side in last week's first leg at White Hart Lane.

While he admits that it will be a difficult match against United, Vorm is confident that Tottenham can book their place in the final.

"At the moment, it has to be the biggest game of the season," he told the club's official website. "For every player there is a huge opportunity to go and play in a major final in an amazing stadium with an incredible atmosphere. It's all for the club and the fans.

"They need to attack because they need to win. It could open up for us and we need to take advantage of the space if we can. We also know it won't be easy and we'll need to play at the top of our game to get a result."

Tottenham or Sheffield United will play Chelsea in the final at Wembley Stadium in March.
