Wigan defender Steven Caldwell felt referee Martin Atkinson's crucial decisions were influenced by the huge Old Trafford crowd in Saturday's 2-0 defeat to Manchester United.
Captain Antolin Alcaraz was dismissed for a second bookable offence after half-time, while striker Hugo Rodallega also saw red two minutes later and Charles N'Zogbia was denied what the Latics felt was a clear penalty with the score still goalless.
"I wasn't even worried he [Alcaraz] might go off for the [second] challenge, to be honest,'' Caldwell told the Wigan Evening Post. "There were tackles flying in from their side - and I know I'm biased - that weren't getting punished, and could possibly have been bookings.
