Anderson says its critical Manchester United improve this season.
The Brazilian, who's been at the club now for more than five years, says the Reds cannot afford a repeat of last season, a campaign that ended trophyless and with Manchester City winning the league.
"We have to do better," he told ManUtd.com. "Manchester United has to win every trophy and we're disappointed if we don't.
"There's always pressure to do well when you play for this club. Last season we lost the league on goal difference and everybody was sad. But we have to forget that and concentrate on this season."
