I don't even know if it'd be an upset when you look at history, our current form, given Benzema is out (was key to creating chances against them each time we did score) and circumstances.
- we're yet to beat Cadiz at home. 2 seasons they've been up we've lost to them at Di Stefano under Zidane and drew 0-0 under Carlo. Even managed to draw them in May when league was won.
- they've beat Atletico, who play similar style to us, albeit at home; they also find it easier to draw games against teams playing cagey
- they got hammered by Rayo, Barca, Celta and Bilbao
After all they have 5 Madrid canteranos in team so no wonder these is how they match up against other teams in the league.
