Barca top the table on 75 points with eight matches remaining, six ahead of Real, who play at relegation-threatened Recreativo Huelva later on Saturday as they try to stay in the hunt for a third consecutive league title.
"Our (Coliseum) stadium is not a place Barcelona like to come and we hope we don't fail and can energise the league," Torres said in a radio interview.
"They don't adapt well to our pitch and that's what we have to very much keep in mind."
Central defender Pepe said Getafe's spirits would be high after they won 1-0 at third-placed Sevilla last weekend.
"They want to play a good match against Barcelona and they will be feeling very confident," the Portugal international said on the club's website.
"We are ready for a very tough month and a half," the Spain international told the club's website.
"For sure all the other teams will be gunning for us," he added. "We have to round off what we have been doing with trophies and we'll fight to win the three competitions although we know it will be very difficult."
Valencia captain Carlos Marchena said their match at home to Sevilla on Sunday was crucial to the financially-troubled club's hopes of playing in next season's Champions League.
"When you get a run of good results it gives you a lift and three straight wins have boosted our confidence," he told the club's website.
