Guardiola conceded the defeat hands the title to Real.
"There are very few things I can blame on the team. We've been on this path for a long time. We had a lot of pressure on us starting in August and we haven't stopped," he said.
"We can't expect to always be up to the standard, but it's a pity that we faltered in the decisive moment.
"We gave it our all and because of that these players know that they have me."
