DOHA: Youssef Msakni on Sunday produced a late goal to power Lekhwiya past Al Sailiyah 1-0 in a tense Emir Cup quarterfinal. Home team Lekhwiya - one of the top teams in Qatar Stars League (QSL) - were stretched by Al Sailiyah before Msakni's left-footed strike from close range settled the issue at Abdullha Bin Khalifa Stadium. After resolute defending and occasional attacks, Lekhwiya - coached by Djamel Belmadi - finally broke the deadlock as Msakni found the top corner of the Al Sailiya goalpost. In the day's last quarter-final, El Jaish take on Al Ahli at the same venue. On Saturday, football giants Al Rayyan and Al Sadd qualified for the semi-finals with wins over Al Kharaitiyat and Al Gharafa respectively. Lekhwiya have never won the Emir Cup. The tournament ends on May 20.
