Input: Question: What year did the player who scored four goals against Rad Belgrade retire? Passage 1:His good results continued in 2016 as he won the title at the Brisbane International in January with John Peers. On April–May they won the BMW Open together. At the 2016 Wimbledon Championships he reached quarterfinals of the men's doubles tournament together with Peers and the final of the mixed doubles with Heather Watson, which they won in straight sets. On July Kontinen and Peers won the German Open Tennis Championships. On August Kontinen won the Winstom-Salem Open playing with Guillermo García-López. It was Kontinen's 10th doubles title in his career. He took the victory of St. Petersburg Open with Dominic Inglot. Kontinen and Peers had a successful end for the year as they won their first Masters title at Paris Masters and the season ending ATP World Tour Finals title. Kontinen reached the top 10 in rankings as a first Finnish tennis player ever.
 Passage 2:During this time, Portugal was not part of a group of teams that were candidates to win titles, but from 2000 until this present day, the team evolved, being present in all the final stages of major tournaments, due to the presence of several world-class players such as Luís Figo, Rui Costa, Deco, Ricardo Carvalho, and Cristiano Ronaldo, who were dubbed as Portugal's golden team, who were considered as the best of the world at their time and among the best in history. Portugal's golden team helped Portugal reach the semi-finals of Euro 2000, losing 3–2 after extra time to eventual winners France, securing the second place at Euro 2004 Final after losing to Greece on home soil, as well reaching the semi-finals of the 2006 World Cup losing to finalist France, after a penalty, leading Portugal to secure the fourth place in the tournament, after losing to 3–1 to hosts Germany, thus being the best result since the 1966 World Cup. Despite losing many players of the golden team, new players such as Fábio Coentrão, João Moutinho, Nani and Pepe helped the Portuguese reach the semi-finals of Euro 2012, losing to Spain in penalties, with Cristiano Ronaldo finishing as joint top scorer of the tournament with three goals. 
 Passage 3:In 1976, led by coach Dragan Bojović, the club won the second league and again provides a placement in the elite, thanks to the four goals by Jovica Škoro, three by Milomir Jakovljević and one by Dragiša Ćuslović, which brought the decisive 8–2 victory over Rad Belgrade, but they relegated again in the same season. In the season 1978–79, they joined the Yugoslav First League, and in that season, Yugoslav powerhouse Partizan suffered a sensational 3–0 home defeat from Napredak. In the season 1979–80, led by coach Tomislav Kaloperović, Napredak finished the championship as 4th and this in front of several Yugoslav top clubs, and qualified finally for the first time for a European competition, the 1980–81 UEFA Cup season, but they were eliminated already in the first round by Eastern Germany's club Dynamo Dresden. It got even worse, because in the same season the club finished the league unexpectedly in the last place and relegated to the Yugoslav Second League and competed there until 1988. In the season 1987–88, Napredak won the East Division of the second league and was promoted to the top tier, but the club could not keep in the first league and relegated for the third time in its history again in the debut season. Napredak remain in the second league until the season 1991–92, the last season of the Socialist Federal Republic of Yugoslavia, and was one of the clubs, which were member of the newly founded First League of the Federal Republic of Yugoslavia. In 1993, Napredak achieved a good six place, but the subsequent 1993–94 season, they relegated to the second league.
