MADRID, Aug. 12 (Xinhua) -- Wednesday's Champions League qualifying game at home to Wisla Krakov will be vital in determining what happens in the near future for FC Barcelona.

    The Catalan side needs to secure a comfortable win in the first game of a two-match tie, in order to give themselves a comfortable margin for the return leg in Poland, which will be held in two weeks.

    However, much more than Barcelona's future in the most important club competition in Europe is at stake, as the game could determine what happens to club President Joan Laporta and striker Samuel Eto'o.

    Eto'o has been the subject of transfer speculation all summer after coach Pep Guardiola said he was not counting on the services of the Cameroon international for the forthcoming campaign.

    Nevertheless, Eto'o has forced himself into the coach's plans after scoring five goals in pre-season. Should Guardiola include him in the side against Wisla Krakov, then he would be unable to play in Europe for another club, effectively ruling out a move.

    Thierry Henry has also been the subject of rumors linking him toa return to England, and the same is also true of the French international - should he play those rumors will end abruptly.

    With Barcelona's Argentinean international Leo Messi representing his country at the Beijing Games, one of the pair is almost certain to start on Wednesday.

    Meanwhile Laporta is awaiting the judgment of the Camp Nou. The Barca president survived a no-confidence vote in July, but received less than 40 percent of the total vote. Should his side struggle, the fans will not wait to voice their opinion against him.

    The game marks the competitive debut of Barca's summer signings, Martin Caceres, Seydou Keita and Dani Alves. The Brazilian defender, signed from Sevilla, is looking forward to the occasion.

    "I am looking forward to the game and to seeing the ground full of fans; I don't think there is going to be a difficult atmosphere. All I can say from my experiences as a rival, that it is very difficult to play here," the full back told Tuesday's El Mundo Deportivo.

    Alves then insisted that with so much at stake, Barca had to take full advantage of opening the tie at home.

    "The fact we are at home has to be vital. We have the obligation to give the fans something to enjoy and also to win the game. Our rivals have to realize just how tough it is to play here, everyone has to be united and pull in the same direction," said Alves.
