The striker struck twice in their 4-0 rout of Almeria this week.
"The important thing was to take three points," Suarez told his club's official website. "We know that if we are not focused 100 per cent we have nothing to do.
"The Primera Division is not an easy place to get three points if you are not fully focused in every game.
"We know we depend on ourselves to win the league title and so we must face every game in the same way.
"All the games are tough but if we face them the way we know how, we will have a good shot at winning, because we are Barca,"
