Sergio’s team head into the game on the back of a shock Copa del Rey exit at the hands of second-tier Tenerife.
Additionally, Valladolid have not won in LaLiga Santander in eight matches, yet the Catalan coach approaches the situation with calm.
“We are not in a delicate, dark or pessimistic period but rather one of concern for the bad run.
“We are frustrated to have played well enough to win but without getting the results.
“We are in the position we deserve be in, we must have perspective; whoever thought this was going to be easy was wrong,” Sergio insisted.
In spite of that, Sergio remained upbeat about the team’s chances of beating LaLiga Santander’s joint leaders.
“It is fortunate that we face Madrid after such a disappointment [for Valladolid]because it is an extra motivation playing such a strong team.
“Why can’t we win? Football is about growing and bouncing back from disappointments.
“We will try to make things uncomfortable for them, force them to run and put away the two or three [chances]that we get.”
