The Uruguayan reaped the benefits of two weeks’ rest after being left out of his country’s internationals and pounced from close range to give Barça the lead in the 28th minute, after the Leganés goalkeeper, Iván Cuéllar, failed to hold a shot from Paco Alcácer.
Suárez doubled Barcelona’s lead on the hour by sliding to send another rebound beyond the hapless Cuéllar and was twice denied a hat-trick. Substitute Paulinho poked in the third in stoppage time for his fourth goal of the season.
There was one negative for Barça, however, as Gerard Piqué picked up a fifth yellow card of the season and is now suspended for the top-of-the-table meeting at Valencia, adding to the absence of fellow centre-back Javier Mascherano.
