City's European fate was all in the cards

Zabaleta's second yellow earns costly banishment against Barca

Manchester City defender Pablo Zabaleta claimed he didn't know why he had been sent off as his side exited the Champions League with a 2-1 loss to Barcelona at Camp Nou, which saw the Catalans advance 4-1 on aggregate.

The Argentine was dismissed for a second yellow card with 12 minutes remaining after City had a strong penalty appeal waved away when Edin Dzeko appeared to have been felled by Gerard Pique.
