Wilder was also critical of the appointment of referee Adam Herczeg, who has been overseeing matches in the English Football League (EFL) since 2022-23, and was in charge of his third Championship game this season.
“We all make mistakes, managers and players included, but it seems we are a testing ground for referees,” he added.
“If there are up-and-coming referees, why hasn’t the referee had more Championship games this season?
“This is a team [Southampton] that has come out of the Premier League against a team that went incredibly close in getting to the Premier League last season. This is a top-notch Championship game – regardless of league positions, it’s high-profile.
“There’s Stephen Martin, who is a top-class Championship referee being a fourth official at one of the games [Bristol City v Ipswich].
“Why aren’t we being given an experienced referee for this fixture? This is the thing I don’t get – the appointment system.
“We all know from experience the best ones go under the radar. Well, certainly, he didn’t go under the radar on Tuesday night.”
