Spurs have lost to the reigning Premier League champions in their three most recent meetings at Wembley, including the 4-2 defeat in last seasons FA Cup semi-final.
Alli is determined to put the result behind him and hopes his team can put in a better performance in Sunday's heavyweight clash.
The midfielder told Tottenham's website, "obviously every game is important and every game means a lot to the players and the fans.
"But there's no hiding how big Sunday's match is to all of us. We've got some history with Chelsea over the last couple of years and we're going out there looking to win the game.
"Obviously, we were disappointed with the FA Cup semi-final against them at Wembley.
"It was another cracking game, a real battle and we played very well on the day, but Chelsea just had the edge. I'm sure it's going to be another great game this time."
