Barca were forced to grind out a 1-0 win at Espanyol yesterday.
â€śWeâ€™re doing well and weâ€™re confident, but we know how hard itâ€™s going to be. We are ready to fight until the end,â€ť said Alves.
â€śWe never lost our intensity, our rivals play football too â€“ they are playing for their lives in this competition, it makes it all very difficult. BarĂ§a may not win all their games comfortably, sometimes we can, other times we cannot."
