Barcelona could be without former Arsenal striker Thierry Henry for their crucial Champions League semi-final return leg against Chelsea at Stamford Bridge.
Henry injured a knee in the 6-2 win over Real Madrid at the weekend and Barca boss Pep Guardiola confirmed he remains a major doubt for their clash with the Blues.
Sources in Spain claim the striker could be out for at least two weeks and if he is ruled out of the tie, it will be another massive injury blow to Barcelona.
The Catalan giants have already lost the services of central defender Rafael Marquez through injury and partner and captain Carles Puyol, who is suspended.
Henry was among Barcelona's better performers in the goalless first leg in the Nou Camp stadium last week but Guardiola will wait before taking a final decision on the striker.
''He's a doubt, to be fair,'' said Guardiola. ''Tomorrow morning we'll see how it is and we'll decide. It is a knee problem.''
However, the Barca coach is confident they will cope with the loss of two of their most experienced defenders.
''Whoever plays in their place will do a great job, I am confident of that,'' said Guardiola.
Guardiola was also quick to make light of their 6-2 drubbing of Real Madrid in the Bernabeu at the weekend.
It was Madrid's heaviest home loss in their history and should have given Barcelona a massive boost ahead of their clash with Chelsea.
But Guardiola insisted: ''What happened in Madrid is history now. We have a marvellous challenge here to get to the final of the Champions League.
''That's what we'll fall to sleep and dream about tonight. The win in Madrid has more merit given the way Real performed in the second half of the season.
''But I go into this game telling my team that Chelsea are going to play the game of their lives. We're going to try and play well and, hopefully, get through.''
Chelsea were dogged and defensive in Spain and Barcelona's players, along with Guardiola, were alleged to have criticised the English side for their tough-tackling tactics.
But the Barca boss insists he will resist the temptation to match Chelsea's physical approach in the return leg.
''How they set the team out in Camp Nou seems fine to me,'' said Guardiola. ''They did a great job, tactically, and got a good result. We'll see how that pans out in terms of the whole tie.
''Whoever gets through will deserve it. Our duty is to score goals. We like a quick, attacking style of play and that is what we will stick to.
''I did not complain about Chelsea's tactics. Chelsea's tactics, for me, were fine. They were efficient.
''If we try to combat Chelsea physically, that will play into Chelsea's hands. We want to play our football around Chelsea. We don't want to get into physical battles with them, because that's their strength.
''I only know one style of playing - that we should attack and try to score a goal.''
