Goals from Ramires and Fernando Torres proved enough to send Chelsea through to the Champions League final at Barca's expense, just days after the Catalan club lost at home to Real Madrid in La Liga, and Guardiola has admitted that his job is in question.
"My future? I'll make a decision in the coming days," said Guardiola.
"I'll talk with the president and we'll decide what's the best for the club."
Since taking over from Frank Rijkaard in 2008, Guardiola has won 13 trophies as manager of the club, including three La Liga titles and two Champions League crowns.
Barcelona are currently second in La Liga but seven points behind arch-rivals Real Madrid with just four games left to play.
