Input: Consider Input: Question: How old was Evrenos Beg when he first fought Pedro's forces at Leontari? Passage:On 6 September that year, Pope Urban VI declared that as James of Baux's successors had forfeited their rights to the Holy See, the principality belonged to him and he devolved its government on Paul Foscari, the archbishop of Patras, who in turn made Pedro vicar general. Pedro was constantly at war with the Despotate of Morea, against whom he even used Ottoman pirates, and the Duchy of Athens under Nerio I Acciaioli. The latter was captured near Vostitsa on 10 September 1389 while trying to sit to talks with Pedro concerning Argos and Nauplia. He had to buy his freedom with concessions to the Navarrese ally, Venice. Late in 1394 or early in 1395, the Turkish general Evrenos Beg invaded the despotate and met Pedro's forces at Leontari. Together the two besieged and took Akova (28 February). After Evrenos returned to Thessaly, Pedro was defeated by the Greeks and taken captive with the grand constable Andronico Asano Zaccaria, his brother-in-law. In December, Venice paid 50,000 hyperpers for the release of her allies.

Input: Consider Input: Question: How long had Kortrijk been a team when Gillenken made his debut for OH Leuven? Passage:Gillekens made his debut for OH Leuven in the 201415 Belgian Cup in the sixth round match against Kortrijk, a 1-3 loss, although that season he was part of the reserves and only fourth goalkeeper behind Logan Bailly, Yves Lenaerts and Senne Vits. Later that season he also played one match in the 201415 Belgian Second Division against Mons. Although Gillekens was promoted to third keeper for the 201516 season, he did not play a single match that season. Following the relegation from the 201516 Belgian Pro League, first goalkeeper Rudy Riou was released while second goalkeeper Yves Lenaerts had already signed for ASV Geel. As such, Gillekens was promoted to first goalkeeper for the 201617 season in the Belgian First Division B. During the winter 201718 transfer window OH Leuven signed Kawin Thamsatchanan, captain of the Thailand national football team and soon thereafter Gillekens was demoted to reserve goalkeeper. Following Thamsatchanan's injury during the 201819 season, Gillekens again became first goalkeeper for a few matches before then being surpassed by Laurent Henkinet. Towards the end of the season, Gillekens was even demoted to third goalkeeper with Thamsatchanan now taking his place on the bench and after the final match of the season it became clear that Gillekens would not be signing a new deal at OH Leuven.
