MADRID, April 2 (Xinhua) -- A classy solo goal by Brazilian striker Ronaldo helped 10-man Real Madrid come from behind to hold leader Barcelona to a 1-1 draw at the Nou Camp on Saturday.

    The result did little to stop Barca's progress towards a second consecutive league title, however, as it remains a comfortable 11 points clear of its arch-rival at the top of the table with seven games left to play.

    The home side took the lead through a controversial Ronaldinho penalty midway through the first half.

    Real suffered another setback soon after when Roberto Carlos, who had conceded the spot kick, was sent off minutes later for saying something to the referee.

    But Real, who was crushed 3-0 by Barca at the Bernabeu this season, salvaged a draw and some pride when Ronaldo roared on to a clever through-ball from Julio Baptista and netted with a deft chip eight minutes before the break.

    Earlier on Saturday, Villarreal secured its first Primera Liga win in five rounds with a 1-0 victory at Real Zaragoza.

    The win pushed Manuel Pellegrini's side up one place to seventh, while Cup finalist Zaragoza remains 10th.

    At the other end, bottom club Malaga looks to be heading for relegation after a 3-0 defeat by fellow struggler Real Sociedad. Enditem
