Barcelona returned to winning ways in La Liga as Lionel Messi and Luis Suarez marked their league returns with goals against newly promoted Leganes.
Messi and Suarez were rested from the starting XI as Barca suffered a shock 2-1 defeat by Alaves last week.
Both started on Saturday, with Messi tapping home before setting up Suarez, and Neymar made it 3-0.
Messi’s penalty and Rafinha’s fine finish stretched Barca’s lead before Gabriel’s superb free-kick for Leganes.
The win moved Barcelona level on points with Real Madrid, who are away to Espanyol on Sunday.

Enrique learns from his mistake
Barcelona coach Luis Enrique accepted the blame for Barcelona’s surprise loss to Alaves after making seven changes before his team’s opening Champions League group game against Celtic.
Despite facing a league game against Atletico Madrid next Wednesday, Enrique took no risks this time against another club promoted from Spain’s second tier as Barca carried on where they had left off after hammering Celtic 7-0.
Leganes, a town of 185,000 people and 11km from Madrid, are playing in La Liga for the first time in their 88-year history. Three years ago they had no training ground and the pitch was full of potholes.
This was uncharted territory for Barca but Enrique’s side were at their ruthless best as they picked off their spirited opponents in a game sprinkled with six yellow cards.
