Doha: Samuel Eto'o debut in the Qatar Stars League turned out to be a huge disappointment after Qatar Sports Club, who signed him this week, went down to Al Sailiya 2-0 here on Friday evening.
Rachid Tiberkenaine scored a brace to put paid to Qatar SC's hope of a win after signing the former Barcelona star.
Rachid struck in the 16th minute followed by a goal from the spot in the 36th to help his side pick up three important points.
In an earlier match, Umm Salal rode on a double strike by Mahmoud Al Mawas (10, 72') to beat Al Ahli 4-1.
Tresor Kangambu scored an own goal in the 54th followed by Ismail Mahmoud's brilliant effort four minutes later to give his side a deserving win.
However, Omid Ebrahimi pulled one back in the 84th minute while a red card to Umm Salal's Adil Rhaili a minute before the goal was their brief moment of celebration.
