Real madrid drew 0-0 with Villarreal on Sunday, keeping the ailing powerhouse in sixth place in the Spanish League.
Madrid lies 13 points behind league leaders FC Barcelona, which beat crosstown rival Espanyol 2-1 on Saturday for its 11th straight league win at home and a club record 15th in all competitions.
The 29-time Spanish league champion has won just one of four league games under coach Juan Ramon Lopez Caro, who replaced the dismissed
Vanderlei Luxemburgo last month to become the team’s fifth coach in the last two-and-half years.
Madrid lost striker Ronaldo, who was playing his first game of 2006, in the 33rd minute of the game at El Madrigal Stadium with what appeared to be a recurrence of the right calf injury which forced him to miss Tuesday’s Copa Del Rey match at Athletic Bilbao.
Villarreal, which has never beaten Madrid in 13 league games, stayed in fifth place.
In other 18th-round games, forward Antonito Ramiro’s equaliser earned racing Santander a 1-1 draw at second-place Osasuna, ending the home team’s perfect record at its stadium in the league this season.
Third-place Valencia drew 0-0 on its visit to Atletico Madrid and
extended its unbeaten run to seven games.
