Mark Hughes has called for Marcos Alonso to race retrospective punishment for a challenge on Shane Long in Southampton's 3-2 loss to Chelsea.
Saints boss Hughes hit out at the standard of Premier League refereeing with a dig over English officials being snubbed for the summer's World Cup.
The former Chelsea striker insisted Alonso should have been sent off for his studs-up tackle on Long at St Mary's Stadium, where the Blues hit three goals in an eight-minute victory blitz.
Spain defender Alonso avoided any sanction for the challenge and a suspension could rule him out of Chelsea's FA Cup semi-final rematch with Saints on April 22.
