Barcelona head coach Xavi Hernandez has said Tuesday’s Champions League match at home to FC Porto could be a potential “turning point” for his side.

Barcelona missed the chance to qualify from Group H with two games to spare, following a shock 1-0 loss to Ukraine’s Shakhtar Donetsk.

Barcelona need a victory over second-placed Porto later today, to go through to the knockout phase with a game to spare.

Xavi has said he’s aiming for qualification come the end of today’s game.

“It’s a very important match, it’s vital. If we win we would be assured of finishing in the top two, after two years without being able to qualify for the last 16,” Xavi said at Monday’s pre-match news conference.

“Lately, things have not been going the way we want but we are on the right path. We believe in what we are doing.

“We need to be very demanding of our ourselves and be self-critical, because we’re no longer at the same level we were a month and a half or two months ago.

“Tomorrow is a great opportunity. We can confirm our place in the round of 16 after five matches. It could be a turning point.”
