Shaw says the fans have never turned on the players this season.
"We always get that extra push at home from the fans and they've also been amazing away from home as well," Shaw told ManUtd.com.
"At home it's always different - when teams come to Old Trafford they can feel that atmosphere and it can be a scary place for other teams. It's a big pitch and United have always been strong at home and won a lot of games here so that's a very important factor as well. I always look forward to playing every game but we're especially looking to make sure we win this one. We've been working hard this week and it's massively important that we get the victory on Saturday."
