Mamelodi Sundowns Coach Pitso Mosimane was unhappy with the officiating in their 1-0 victory over Bloemfontein Celtic, in the Telkom knockout first round match at the Lucas Moripe stadium in Atteridgeville last night. Uruguayan midfielder Gaston Sirino scored the only goal in the second half to elevate his team to the quarterfinals. Mosimane also suspects that Sirino’s goal might have been offside.
