Here are three Premier League fixtures this weekend that could potentially yield shock results:

Arsenal vs Brighton: A Clash of Unbeaten Sides

Arsenal and Brighton have both won their first two games of the season, setting up an intriguing encounter at the Emirates. Arsenal's narrow win at Aston Villa last weekend could have easily gone the other way, and Brighton will be eager to capitalize on any complacency. If the Gunners don't start strong, Brighton might take advantage and secure a surprise result.

West Ham vs Man City: Can the Hammers Stun the Champions?

Pep Guardiola's Manchester City has won two from two, but their trip to West Ham could be a challenge. The Hammers have bounced back from an opening-day loss with a 2-0 win at Crystal Palace and look to be finding their footing under Julian Lopetegui. City will need to be ruthless to avoid dropping points at the London Stadium.

Chelsea vs Crystal Palace: A Tricky Test for the Blues

Chelsea's 6-2 thrashing of Wolves last weekend was an encouraging display, but their 2-1 loss to Servette in the UEFA Conference League play-off second leg brought them back down to earth. Crystal Palace, meanwhile, desperately needs points on the board, making this a potentially tricky fixture for Chelsea at Stamford Bridge.
