The Spanish champions are now without a win in their last four La Liga matches, but Busquets has insisted that his side deserved to pick up all three points on Sunday evening.
"We were the better team but did not create enough clear-cut opportunities," Busquets told reporters. "It does not matter if you dominate the game in terms of possession and position if you cannot score more goals.
"These matches are always difficult, Valencia are a team who can defend deep and are well organised, particularly if they have taken the lead. We thought they would come forward more after our equaliser but they did not."
Barcelona currently sit second in La Liga on 15 points, one point behind the leaders Sevilla.
