Barcelona coach Pep Guardiola has attacked Real Madrid rival Jose Mourinho for his ref swipe. Mourinho wrote off his old club Chelsea's chances of beating Barca in the Champions League semi-final later this month.

He hinted at a UEFA conspiracy when he said "we know why" Chelsea will not be in the final against Bayern Munich or Mourinho's Real Madrid.

Barca boss Guardiola said: "We thank Mourinho for his confidence but all four teams have a chance - and we appreciate that he thinks we can reach the final."
