Cambiasso: Inter Milan wary of Tottenham threat
And Cambiasso said: "Tottenham is a club with history and we know that all the English teams will be difficult to beat.
"I am optimistic we will get into the knockout stages, but the group will not be easy.
"We are the champions of Europe and people will give us the title of favourites in this group - but we have to show it on the pitch."
Cambiasso added: "The challenge for Inter this season is, at a minimum, to reach the final in London."
