The Portuguese said: "Spurs are one of the top teams in the country - not a title contender because they are too far away, but I say honestly they are a Champions League contender. They can reach that level.
"They have some of the best players in the country, a very good manager and are a very difficult opponent.
"It is a really big game. The difference between us and Spurs is seven or eight points, but the reality is they are a top team in terms of their quality and ambitions, and a team of our level, so it is a big match."
