To be fair to him, they are a very good team and I wouldn't be at all surprised if we lose on Sunday for that exact reason. That said, I still think we're favourites after their poor showings against Liverpool, Everton and Sunderland (Sunderland!) not to mention in the Champions League.
However, people underestimate Guardiola entirely when they say you can beat his teams by pressing. What makes him the best manager in the world is his ability to identify what isn't working and change it quickly. If people do start beating us by pressing, after a week he'll have changed his game plan so that it won't work any more. They're thinking of Mourinho, or Wenger, who like to do the same thing every game whoever they're against. Come to think of it, most sports journalists have probably forgotten it's possible for a team to have more than one tactical style.
EDIT: I've just looked at Tottenham's results for teh season and it's left me feeling much more optimistic about the game. Bar the 4-0 at an awful Stoke (who we also put four past, let's not forget) and a 5-0 thrashing of a League One team (God forbid we would ever get a cup draw against a non-premier league team) they've not looked great. 9 goals in their other 7 games. Most of their best play recently has come from Son, stop him and we have a very good chance. We've managed 3 goals a game this season to their 2, so this game will likely hinge on the performance of our defence. On the plus side, Kane's injured and Janssen has been shite.
