Barcelona midfielder Sergio Busquets was disgruntled that his team failed to see out the win against Real Madrid after going a goal ahead in the second half.
Cristiano Ronaldo equalised in the 82nd minute to prolong Madrid's flailing title challenge and the 22-year-old believes if Barca had won at their rivals' ground, the league would have been out of reach for the capital club.
''It is clear that when they only had 10 men we could have won and wrapped up the league,'' the World Cup winner admitted to Spanish publication AS.
Busquets was also not happy with the state of the pitch in Madrid either as Barcelona's passing game failed to materialise in its usual swashbuckling fashion.
"The grass was not as fast as we would like to implement the football we like to do," he complained.
"We had to play many more passes than if the grass was faster."
However Busquets reflected on the positive aspects of the result in spite of conceding late on:
"We're happy with the points earned and we stay at the same distance with one game less to play. We'll prepare for the [Copa del Rey] final now.''
