Daniel Alves admits he was surprised Barcelona's clash with Sporting Lisbon failed to attract a full house to the Nou Camp.

The Brazil fullback said: "It was strange that it was not full, it is a bit strange. Whenever I came with Sevilla to the Nou Camp the attendance has been much higher."

Barca striker Thierry Henry also said: "The number who come to watch us depends on who we're playing and whether we are winning. I'm sure people will gradually return."
