All we know both teams from the same city but totally different vision of football. Atletico more compact while Galacticos more open, offensive. Despite of prestige in the city RM has more to lose here. In case of dropping any points Barcelona would take 10 or more points ahead. So I expect a Real Madrid going all out and having all the available attack men possible to build actions and try go to open the wall.
In recent Cola Del Rey battle Real managed to take a lead in first half, unfortunately for rest of my bets decided to fall back And goal the advantage of 0-1 and the return in the Bernabeu. In this case it won't happen again.
Stats speak loud about possible scenario, in last 5 league outgoings R.Madrid achieved 6 corners against Espanyol, 5 corners against Betis, 4 against Villarreal, 6 against Huesca and 4 against Eibar.
You should notice that Atlético de Madrid is the second Spanish team that takes the most out of the corner in La Liga (11,05) which give 6.36 in average receiving.
