Barcelona captain, Andres Iniesta believes Barcelona lost control after going two goals up, but ending in a draw.
Barcelona were ahead with impressive strikes from Messi and Rakitic.
But they fell by the wayside, and Iniesta hopes they can work on the errors.
“The end is unexplainable, we lost control when we needed it and facilitated the opposition,” he told Canal Plus.
“These things happen, we analyse it so that it doesn’t happen again. The last two weeks we’ve lost four points, which makes things tighter.
“Now we change mindset because we are playing for a title and have to think of what’s next.
“We had a 2-0 lead, the match was good. We lost the control we had throughout the match and two points escaped us.”
Atletico Madrid could move level with Barca at the Liga summit if they overcome Atheltic Bilbao on Sunday.
