Amrabat was the creator once more for Leganes' best chance before the break when he released Alexander Szymanowski inside the area, but the Argentine's curling effort was turned to safety by the in-form Ter Stegen.
The Catalan club opened a seven-point lead over Valencia and an 11-point advantage over Real Madrid and Atletico Madrid, which meet later Saturday at Wanda Metropolitano Stadium.
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 Barca the lead in the 28th minute, after Leganes goalkeeper Ivan Cuellar failed to hold a shot from Paco Alcacer. Suarez's second in the 60th was a rebound shot after Cuellar parried a shot by Lionel Messi.
"I wasn't anxious about scoring, I was just trying to feel good", he said after the game.
"We already know our forwards always relate well with our opponents' goal and that sooner or later, the goals will come".
In contrast, just as in the first-half, Barca were ruthlessly efficient in front of goal to double their lead on the hour mark.Читайте также: Florida Democratic Party leader resigns in wake of scandal
However Gerard Pique will miss next weekend's game against Valencia, as the central defender was given a yellow card for wrapping his arms around Nordin Amrabat, the striker on loan from Watford.
Barcelona also plays at Juventus on Wednesday in the group stage of the Champions League.
Valverde said: "The result was misleading and excessive because Leganes made it hard for us and had a great game, while there were times when we weren't brilliant".
Leganes, playing only in its second season in the first division, wore a specially designed purple shirt to promote the fight against gender violence.
It was the 10th league loss for Alaves, which remains in 18th place.При любом использовании материалов сайта и дочерних проектов, гиперссылка на обязательна.
