Lazio goalkeeper Federico Marchetti has insisted that his side faces a "battle" against Tottenham Hotspur when they meet in the Europa League on Thursday.
The Italians go into the match at the Stadio Olimpico two points clear of Spurs at the top of Group J and would secure their progression with a win.
"Tottenham are one of the strongest sides in the Europa League," said Marchetti. "We will try to win in order to secure qualification, but it will be a battle."
Lazio earned a goalless draw at White Hart Lane when the two sides met in September.
