Hakan Ünsal is remembered by many for his rocket left foot and his pinpoint passing as well as his ambition. He played most of his career at Galatasaray after joining from Karabükspor in 1993–94. After being a part of the squad that won the UEFA Cup in 2000, Ünsal moved to Blackburn Rovers of the English Premiership in January 2002. Blackburn had hoped to sign him in time for their upcoming appearance in the 2002 League Cup Final, however a work permit delayed his debut and he missed them lifting the cup. His return to Galatasaray was rapid as he was once again in Galatasaray colours for the 2002–03 season. After leaving Galatasaray following the 2004–05 season, he had a brief stint with Çaykur Rizespor before retiring from football.
