Real Valladolid coach Sergio Gonzalez believes that playing against Real Madrid at this point of the season is a dangerous task.
Los Blancos have been knocked out of three competitions in the past week which does not work in the favour of Valladolid, according to the 42-year-old tactician.
"They are a wounded lion, they have a lot of absentees, but they are a hurt team of top players with self-esteem," he told the press conference.
"They will come to vindicate themselves, but we will try to make it difficult for them.
"I think it's the worst week of the season to host Madrid, as now they know that they only have the league to play for and their first rivals are ourselves.
The game will kick off on Sunday at 8.45pm CET at Estadio Jose Zorrilla.
