Question: What team did Drogba score the winning goal against in the final? Passage:In July 2004, Drogba moved to Premier League club Chelsea for a club record £24 million fee, making him the most expensive Ivorian player in history. In his debut season he helped the club win their first league title in 50 years, and a year later he won another Premier League title. His displays saw him named in the FIFA World XI for 2007. In March 2012, he became the first African player to score 100 Premier League goals. Just two months later, he scored in Chelsea's 2012 FA Cup Final win over Liverpool to become the first (and , the only) player to score in four separate FA Cup finals. He also played in the 2012 UEFA Champions League Final, in which he scored an 88th-minute equaliser and the winning penalty in the deciding shoot-out against Bayern Munich. After spending 6 months with Shanghai Shenhua in China, and one and a half seasons with Turkish club Galatasaray where he scored the winning goal in the final of the 2013 Turkish Super Cup, Drogba returned to Chelsea in July 2014. With a career record of scoring 10 goals in 10 finals winning 10 trophies at club level, Drogba has been referred to as the "ultimate big game player." He joined Canadian club Montreal Impact in 2015 as a Designated Player and played 41 matches over two seasons, scoring 23 goals. Drogba became a player–owner for Phoenix Rising of the United Soccer League in 2017, and retired a year later at the age of 40.

Question: In what modern country is Barbitanya located? Passage:Bahlul Ibn Marzuq (died 802) was born in the current term of La Puebla de Castro (Huesca), was a Vascon-Muslim, the son of a local lord named Marzuq ibn Uskara ("son of the Basque"). He rebelled in Zaragoza against the Arab-Muslim government of Al-Andalus in 798, and in 800 conquered Huesca from the Banu Salama. His rebellion carried popular support, especially after public backing by theologian Ibn al-Mughallis. The emir sent the Huesca native, general Amrus ibn Yusuf, and Zaragoza and Huesca were retaken (c. 801). Bahlul fled to Pallars where he was killed by his lieutenant Jalaf Ibn Rashid (802), who at the time held Barbitanya (Barbastro). The adventures of Bhalul were collected by the Muslim historian and geographer Ahmad ibn Umar al-Udri (1003-1085) in the popular epic poem written in Arabic known as "the archuza de Bahlul".
