The Eagles have been dragged into a Premier League relegation fight after a run of 12 games without a win in all competitions.
Although Palace sit 12th in the table ahead of Sunday’s trip to leaders Arsenal, the club are just three points above the relegation zone.
Wednesday’s defeat at Brighton was the final straw for Vieira, who was unable to build on his impressive first season at Selhurst Park.
