Warren Gatland has highlighted his side’s failure to deal with the “disruptive” change of referee in his side’s World Cup quarter-final defeat by Argentina and suggested the wrong decision was made when Guido Petti escaped any sanction for a shoulder charge on Nick Tompkins.
Wales scored the opening try through Dan Biggar after an impressive start to the match but on 15 minutes the South African referee, Jaco Peyper, pulled up with a calf injury and was replaced by Karl Dickson of England, who was acting as an assistant referee.
