Tottenham Hotspur manager Mauricio Pochettino believes that his side will be in for a difficult game when they face Sheffield United in the second leg of their League Cup semi-final.

The North Londoners claimed a 1-0 victory in tonight's first leg at White Hart Lane thanks to a late penalty from Andros Townsend.

"It was a tough game," he told Sky Sports News. "I am happy for the result but we need to play the second leg in Sheffield and win. Sheffield United played very aggressive in the first half and cut every action, they played narrow and deep and it was difficult.

"Now we need to look forward and try to win the second game. It will be a difficult game, they played well and we need to go and be focused."

The second leg will be played at Bramall Lane next Wednesday.
