Barcelona coach Pep Guardiola knows life has become much harder for them in Group F following their Champions League defeat to Rubin Kazan - but he had few complaints about his side’s performance despite the 2-1 defeat.

Holders Barca had not suffered a defeat in Europe since last December, when, having already qualified for the last 16, a much-weakened side were beaten by Shakhtar Donetsk, but that run came to an end last night against a hard-working Rubin side.

The result has made things extremely tight in Group F, with Barca now level on four points with Rubin and Dynamo Kiev, while Italian giants Inter Milan are just one point behind, and with two of their final three games involving difficult winter trips to Ukraine and Russia, Guardiola knows his men have a fight on their hands to progress.

He said: “The group has become very tight, and we all have a chance to get through to the last 16.

“Now we will try and get a good result in Russia. We are going to fight.”

Guardiola could find little to criticize his side for during the reverse against Rubin, though.

Barca fell behind inside the opening two minutes when Alexander Ryazantsev surprised everyone with a long-range piledriver, but the home side drew level through Zlatan Ibrahimovic just after half-time and had plenty of chances to add more goals only to be denied by a mixture of poor finishing, good goalkeeping by Sergei Ryzhikov and bad luck.

The hosts were then hit with a sucker-punch in the 73rd minute when Rubin broke away to net what would prove to be the winning goal through Gokdeniz Karadeniz.

“Football is like that,” said a pragmatic Guardiola. “With the statistics that we had, in any other sport we would have won, but not in football. I honestly think that we had a good game, but results do not always show that.

“We’ve had a good game, but we’ve lost, and you cannot do anything about that. It’s disappointing because we could have taken an important step towards the last 16.”
