Barcelona defender Jordi Alba has admitted that he will have to improve his behaviour on the pitch after throwing the ball in Arjen Robben's face in his side's 4-0 Champions League loss against Bayern Munich last week.
The Spain international threw the ball at the Dutch attacker in frustration as his side lost 4-1 at the Allianz Arena in the first leg of their semi-final tie and was consequently handed a yellow card for his action, which means he misses the return game.
"I know that I have to improve in certain areas," the wing-back was quoted as saying by Marca when questioned about the incident with Robben.
"Unfortunately, I will not be able to play in Wednesday's match against Bayern.
"However, I trust my team-mates to stage a comeback at Camp Nou."
Wednesday's second leg is scheduled to kick off at 20:45CET.
