Spanish football title rivals Barcelona and Atletico Madrid stayed locked together at the top of La Liga after they played out an intense nil-all draw with few genuine chances at the Calderon.
Not even the introduction of Barca's fit-again World Player of the Year Lionel Messi at halftime or Brazil forward Neymar with just over 20 minutes left could break the deadlock and both teams have 50 points at the halfway stage of the campaign.
The result was good news for third-placed Real Madrid, who can close to within three points of the joint leaders with a win at Espanyol tomorrow.
