Barcelona coach Ernesto Valverde praised his team's motivation levels after they secured the Liga title on Sunday.
A Lionel Messi hat-trick led Barca to an entertaining 4-2 win at Deportivo La Coruna to seal the club's seventh league title in 10 seasons.
Valverde said his players' desire to win was key to their success, which was sealed with four games remaining in the campaign.
"It is the most complicated. Win once, we all have moments when we win once," he told Movistar .
"The hard part is winning many times. You have to reactivate yourself again.
