Spanish leader Real Madrid piled the pressure on Barcelona by taking a provisional 13-point lead over its rival with a 4-0 victory over Racing Santander Saturday. Cristiano Ronaldo headed home his league-leading 28th goal after six minutes and the host played against 10 men from the 39th when Domingo Cisma was red-carded for handling for a second time. Karim Benzema scored a goal either side of the break, while Angel di Maria marked his first appearance of 2012 with an impressive 73rd-minute strike as Madrid prepared for Tuesday's Champions League last-16 match at CSKA Moscow with its 18th win in 19 league games, which includes eight straight victories. “We won easily, we won without much shine or too much effort, but we won well,” Madrid coach Jose Mourinho said. “We won without having to suffer, which is the most positive aspect.” Three-time defending champion Barcelona will need to beat Valencia Sunday at the Camp Nou to remain within 10 points of its biggest rival. As encouraging as Di Maria's and Sami Khedira's returns from injuries ahead of the CSKA match were, Di Maria and Ronaldo both limped off after the final whistle. Di Maria appeared to hurt the same right thigh muscle that had sidelined him since December, while Ronaldo's ankle bothered him. Madrid was keen to end a recent run of conceding the opener at Santiago Bernabeu Stadium as it charged out of the start buoyed by the return of Kaka and Marcelo to the starting lineup, while Raphael Varane made a rare start at centerback to shift Sergio Ramos wide. Di Maria and Khedira both got minutes as second-half substitutes while Gonzalo Higuain watched from the bench as Mourinho looked to save the Argentina striker for Moscow. “It's important to have as many players as possible available now that we're entering a period when we'll play games every three days,” Mourinho said. Also, Getafe striker Nicolas “Miku” Fedor won and scored a late penalty to salvage a 1-1 draw against Espanyol, and Sevilla ended an eight-game winless slide with a 2-0 win over Osasuna. Raul scores 400th goal Raul scored his 400th professional goal to set Schalke 04 on its way to an emphatic 4-0 win over VfL Wolfsburg Sunday, handing visiting coach Felix Magath an unhappy return to the club he left just under one year ago. Raul, signed by Magath before the start of last season, opened the scoring in the 10th minute. Klaas Jan Huntelaar helped himself to two goals and missed a penalty and Joel Matip scored the other. “I didn't know it was my 400th goal but I'm happy, it's nice the reach this milestone,” Raul told Sky. “The best thing was that we won today.” The 34-year-old Spaniard scored 323 goals for Real Madrid and 44 for Spain before adding another 33 in only 18 months at the Gelsenkirchen-based club. Borussia Dortmund leads with 49 points, followed by Borussia Moenchengladbach on 46.
