Barcelona winger Pedro has warned his side that Atletico Madrid have more weapons than Diego Costa ahead of Wednesday's Champions League quarter-final second leg.

Costa is a doubt for the clash at the Vicente Calderon after limping out of the first leg last week, which ended in a 1-1 draw at the Camp Nou.

However, Pedro has insisted that Atletico will be a serious threat even without the services of their leading scorer.

"Diego Costa is a very good player and fundamental for them, but if he doesn't play they have other options," Pedro told the club's official website.

All four meetings between Barcelona and Atletico this season have ended in draws.
