Fiorentina boss Vincenzo Montella has warned that Tottenham are better than their league position suggests.
The clash between the Serie A side and Spurs promises to be a close encounter with neither side having fulfilled their potential so far this season.
Tottenham are in seventh in the Premier League and Fiorentina are currently sitting in eighth in Serie A, but the Italians' coach believes Spurs shouldn't be underestimated.
"At the moment their position in the Premier League table doesn't do justice to their value and the high level of the team.
"You also have to consider that they could turn to the market in January and add to what is already a strong midfield, but I know my players and they will give their all.
"We know that it is difficult playing in England because the public are always very passionate, but our fans will also give us a boost at the Stadio Artemio Franchi.
"We will do our best to get through and raise the ranking of Italian football."
The first leg is on February 19 at White Hart Lane and the return in Florence will be on February 26.
