The Argentina international is wary of Spurs given their impressive start to life in the Champions League.
“They are a good team who can put you in difficulty on the counter attack,” Zanetti said.
“We must be careful on set-pieces and have to be very concentrated.
“The criticism after the Cagliari game doesn't interest us. We won at a difficult ground and, even if there are things to improve, the important thing was getting three points and we managed to do so.
“We respect all the teams in our Champions League group, which is very balanced. We must give the maximum to qualify as soon as possible.
“Benitez has a team available to him that allows him to play with different formations provided that we are all healthy and we train well.”
