Josep Guardiola has refused to be drawn on speculation linking Barcelona with Premier League stars Dimitar Berbatov, Didier Drogba and Emmanuel Adebayor.

Reports claim the Nou Camp boss is interested in Spurs striker Berbatov, Chelsea's Drogba and Arsenal forward Adebayor in a bid to strengthen his side further ahead of his first campaign in the hotseat.

But Guardiola was remaining tight-lipped after watching his Catalan giants cruise to a 6-0 friendly win over Hibernian at Murrayfield in his first game in charge on Thursday night.

"I'm not here to speak about them," he said. "I have many excellent players and I am working with them. All good players are interesting and those players are interesting, but there are many, many good players, in England, Germany, everywhere."

Asked whether he was preparing to make a bid, Guardiola added: "I don't know. The sporting director can talk about that better than me."

Eidur Gudjohnsen helped himself to a double and Lionel Messi, Pedro, Bojan Krkic and Yaya Toure all claimed a goal apiece in a game where Messi stole the show in the 45 minutes he was on the park.

Guardiola is now seeking a quick resolution over the Argentinian's participation in the Olympic Games in Beijing this summer – a move Barcelona are opposed to.

He said: "[Fifa president Sepp] Blatter has to make a decision because we have been waiting a long time for the decision.

"If he has to go according to the law, he goes. If he is to stay according to the law, he stays. But a decision has to be made as quickly as possible."

Meanwhile, the club's sporting director Txiki Begiristain says Barca will only release Messi if they are threatened by Fifa sanctions.

On Wednesday, Blatter said that clubs must release eligible Under-23 players for next month's Olympic soccer tournament, but Begiristain said the circular received by Barcelona made no reference to any punishment.

"The Fifa circular doesn't oblige us to do anything," Begiristain said.

"There is no talk in it about sanctions or punishment for the club, only about the Olympic spirit. But there is nothing else new in it, so it is our understanding that everything else remains the same," he said.

Begiristain said that the club's refusal to release the 21-year-old had been prompted by the fact they had to play a Champions League qualifier during the Olympic Games.

"We understand the importance of the Games but Fifa and the AFA (Argentine Football Association) need to understand the importance of the Champions League," he said.

The AFA have said they expect Fifa to make a final decision over the matter on Tuesday.
