How dare you sir! Seriously, I'm glad we got Chelsea in the semi, they are going to be favourites for the cup so lets bite the bullet. Tottenham could beat Chelsea of course, one of the few teams to have done so this season, and I was quite encouraged by the amount of possession Man Utd got in the quarter before Herrera went off, they are not invincible.
The Arsenal vs Man City game will be really tight also, on current form I'd fancy the Mancs to take the spoils, but Arsenal can give anyone a game when all cylinders are firing.
