The third-placed side are looking to boost their chances of a third place finish when they host Ernesto Valverde's men in an intriguing La Liga encounter on Saturday
Torres scored the sole goal on Wednesday as Atletico recorded a hard-earned victory over Villarreal that sent them six points clear of fourth-placed Sevilla in La Liga.
The top three sides in Spain automatically qualify for next season's Champions League group stages and, with just four matches of the season remaining, Diego Simeone's men are well-placed to achieve that feat.
Winning at Villarreal, who sit sixth, was seen as significant in that bid, although Atleti will face a Bilbao side unbeaten in three games.
"Adding points is important to bring us closer to our objective," Torres told Canal+.
"Wins bring us closer to the objective. We know that for us, for the year coming, and for the club, it is essential to be in the Champions League.
"The sooner we begin to add points and reach that goal, the better it will be for everyone."
Atletico, knocked out of the Champions League quarter-finals by arch-rivals Real Madrid last week, are unbeaten in 11 La Liga fixtures.
They have recorded three successive wins, conceding just one goal in the process.
Bilbao, who sit eighth, were held to a 1-1 draw against a 10-man Real Sociedad on Tuesday.
Aritz Aduriz scored in that match, continuing his excellent season. The forward has bagged 15 goals in 28 league fixtures.
Atletico have won the last five encounters between the two sides, including a 4-1 road win earlier this season. Antoine Griezmann scored a hat-trick on that occasion.
Bilbao's last win at Atletico came in January 2011, when Gaizka Toquero scored both goals in a 2-0 triumph.
