Spanish giants Barcelona have defeated Osasuna 3-0 in La Liga at the El Sadar Stadium.
After a goalless first half, the Catalans finally broke the deadlock through Luis Suarez who scored with a simple tap-in after a fine pass from Alba.
Argentina ace Lionel Messi, who made his 500th appearance for Barca on Saturday, doubled their advantage in the 72nd minute by chipping the ball over the keeper to make it 2-0.
Messi then scored the 3rd for Barcelona and his second of the match in injury time to seal the vital victory for the visitors.
