Besiktaş Istanbul
In the early 2000s, Besiktas Istanbul was Turkey's most successful football team. They have won 14 Turkish league championships and were champions without losing a single game until 2016, in front of their own fans, when they lost to Fenerbahce at home by 2 goals (1-3). They also enjoyed success at international level, beating Lazio Roma in the 2003/04 UEFA Cup after an unlucky extra-time goal ended the game before half-time! It's crazy how much history these clubs are making right now.
