This Sunday (21:30, Canal + 1) Real Madrid visits Vallecas with Cristiano Ronaldo, who has scored against Rayo in both the matches he has played against them (match day 5 and 24 last season). The Portuguese player made his debut in this Madrid derby, which hadn't taken place since the 2002-2003 season, with a hat-trick in the Santiago Bernabéu. Real Madrid had to stage a comeback and finished the match with a resounding 6-2 win with three goals from Ronaldo, two of them penalty shots. His contribution in Vallecas was quite different. He only scored one goal, but it was decisive and will always be remembered as his back heel kick earned the Whites victory and left the stadium open-mouthed.
