"We will file a complaint to the match commissioner against Stade Malien for the treatment we got," Alaa Abdul-Sadek was quoted as saying on ENPPI's official website.

"We asked Stade Malein's president to intervene and solve the electricity problem but our words fell on deaf ears.

"Lights were turned on with 15 minutes remaining on the session following the intervention of Egyptian ambassador to Mali Hamed Shokri."
