Gerardo Martino calls for calm

Barcelona boss Gerardo Martino has admitted that his side must be 'calm' in tonight's Champions League quarter-final first leg against Atletico Madrid.

The two teams have met three times already this season, with the shares spoiled on each occasion.

"We can't go out there and play a wild game; we need to keep some order," Martino told reporters at a press conference.

The last time that the pair met at the Camp Nou was in a La Liga clash last season, when Barcelona were 4-1 winners on their way to claiming the title.

The second leg will take place at the Vicente Calderon next week.
