Barcelona coach Frank Rijkaard admitted that Primera Liga leaders Real Madrid have the upper hand, as Barca failed to reduce the deficit with a 1-1 draw at Sevilla. Xavi secured a point for the Catalans 14 minutes from time, after Diego Capel put the home side in front with a 34th minute striker at Ramon Sanchez Pizjuan. Barca were missing a host of key players like Samuel Eto'o, Yaya Toure and Gianluca Zambrotta, but Rijkaard admits they have to work harder in order to catch up with the holders. "Real are the strongest team at the moment," the Barca coach said after the game. "We are in three competitions and have to concentrate on getting our own work done. We have to keep on working hard and accumulating points." Real will entertain Valladolid at Santiago Bernabeu on Sunday, knowing that a win would see them fly eight points clear at the top.
