The SPL leaders have not lost a goal on the road in the league this season and have not dropped an away league point since February.
Foster spent last season on loan at Ibrox last season and will face last term's team-mates at Pittodrie as captain of the Reds for the first time.
But the Dons skipper is only concerned with leading his team to victory over the enemy on Saturday.
"If the performance is there, there's no reason why we can't get a result," Foster told BBC Scotland.
"Rangers at Pittodrie is always special. The crowd are always absolutely buzzing and I'm sure it'll be a good game.
"There's no point in us going into the game if we don't think we can [win]. Six games this season away from home and they haven't lost a goal, it's quite impressive.
"Aberdeen v Rangers at Pittodrie is different from Rangers going anywhere else in the SPL. We'll make it difficult for them and hopefully we can breach their defence.
"Obviously, I want to do well for Aberdeen. I'm the captain and I want to win games. Rangers coming to Pittodrie is always special, a little bit more so for myself and I want to go out there and get the three points.
"At Pittodrie, Celtic are the only team to have beaten us over the 90 minutes and it's important that we go out and show the same desire that we did down at Parkhead and I'm sure we can get a result.
"We'll be the home team, we'll have, I would imagine, a big crowd supporting us right from the first whistle. For them, and for ourselves, we want to put in a great performance."
