(Reuters) - Barcelona have another chance to secure qualification for the knockout rounds of the Champions League when they host Porto, and Xavi Hernandez's side need the fans support for this vital game, the manager said on Monday.
The Spanish side looked to be easing towards a last 16 place after winning their opening three games, but defeat to Shakhtar Donetsk in their previous match leaves progress still in doubt, having failed to emerge from the group stage in the last two seasons.
