Soccer:Barcelona manager Pep Guardiola has rejected Zlatan Ibrahimovic's claims that Jose Mourinho had been right to argue that Barcelona are beneficiaries of dubious decisions at the Nou Camp following last night's 3-1 victory over AC Milan in the Champions League quarter-finals.

Two Lionel Messi penalties and Andres Iniesta’s cute finish ultimately rendered Antonio Nocerino’s away goal midway through the first half just a consolation and Guardiola was convinced that both penalties were correctly awarded.

Ibrahimovic, who left the club under a cloud in 2010, was left ranting about Dutch referee Bjorn Kuipers decisions to penalise Alessandro Nesta for pulling Sergio Busquets's shirt at a corner for the second penalty.

"Barca don't need these things. They are the best team in the world," Ibrahimovic fumed. "I start to understand Jose Mourinho when he talks about what happens when you come here to play against them. Now I have seen it first hand and I understand it more and more."

Guardiola dismissed the idea there was any doubt over either penalty when asked about Ibrahimovic's comments."I have seen replays of both incidents and they were clear penalties," Guardiola said."Ibrahimovic wants to make friends with Mourinho, but it is now five times in a row we have made the semi-finals. We do our talking on the pitch.

“They were fouls in the area and they were given so they were two penalties. This is what I have been taught since I was a child. If Ibrahimovic says it is thanks to the referees then fine, but we have qualified five times and the players speak on the pitch, which is where they should do their talking.”

The reigning European champions may face a repeat of their 2009 semi-final with Chelsea as the Londoners hold a 1-0 lead over Benfica going into the second leg of the their quarter-final tonight, but Guardiola refused to count the Portuguese side out of the tie.

“Chelsea still have a game to play, in the Champions League everything is very difficult. We have to be cautious with Benfica, Chelsea have a very good team but everything is possible,” he said.

Milan boss Massimiliano Allegri admitted that the best team had won, but he was not happy with referee Kuipers’ decision to award the second penalty just before half-time. Allegri said: “The best team has qualified. We committed a terrible error for the first penalty, the second is more dubious and the referee gave it too quickly.”

Milan have failed to reach the Champions League last four in any of the last five seasons but Allegri thinks his side are making progress. “Next year Milan will be much more competitive, this year we have gone a step further in the Champions League and as much as it hurts we must now concentrate on the league,” he said.

Allegri makes Barcelona tournament favourites now, as they bid to become the first side to retain their European crown in the Champions League era. He said: “Barcelona were the favourites before and they continue to be so.”
