Barca plays down loss of Messi

Barcelona assistant coach Jordi Roura played down fears for the fitness of Lionel Messi on Tuesday while Paris Saint-Germain coach Carlo Ancelotti insisted his team can still win its Champions League quarterfinal tie.

PSG came from behind twice to draw 2-2 with the Catalans at the Parc des Princes in a pulsating first leg, with Blaise Matuidi's stoppage-time shot squirming through the grasp of visiting 'keeper Victor Valdes.

Xavi Hernandez had given Barcelona the lead from the penalty spot in the 89th minute after Zlatan Ibrahimovic had canceled out Lionel Messi's first-half opener.

Conceding so late on was a blow for the Spanish league leader, but the two away goals give it the edge ahead of the return.

However, Barca's night was marred by injuries, with centerhalf Javier Mascherano being carried off in the second half and Messi not reappearing after the break because of a hamstring injury.

"Messi has a small hamstring problem," said Roura, who appeared before the press after the game despite coach Tito Vilanova returning to the bench for the first time since spending two months in New York undergoing cancer treatment.

"We will find out more about the injury tomorrow (Wednesday)," he said, although Messi appeared to be walking without any trouble as he made his way through the mixed zone after the game.

"Mascherano has a knee ligament injury and will be out for between four and six weeks.

"We will try to ensure that these injuries do not have an impact on the second leg," he said, with the return to come at the Camp Nou next week.

"They are two very important players to us, but we have a big enough squad and we certainly have players who are capable of filling in."

The game itself was marked by some contentious decisions, with Barcelona not happy that Ibrahimovic's strike in the 79th minute was allowed to stand.

They felt that German referee Wolfgang Stark should have disallowed the goal for offside.

"There were decisions made by the referee which could at least be contested," said Roura, who said he was not surprised by the battling nature of PSG's performance.

Ancelotti said he could not fault his team's performance, but bemoaned Starks's decision to award the visitor a late penalty and admitted that the result leaves his team with a lot of work to do in the return.

"I don't think it was a good result," he said. "We played very well in the first half, but the two goals we conceded were gifts.

"You have to defend against Barcelona, but when you have the ball you will have chances to attack and be dangerous.

"I am confident that we can do something there."
