Besiktas boss Slaven Bilic is a big fan of Arsenal midfielder Aaron Ramsey.
Besiktas meet Arsenal in a Champions League qualifier this week.
"'He is Arsenal's best player. Their most important player," Bilic said of Ramsey.
"There is a lot more fuss on a daily basis about Jack Wilshere but so far on the pitch, it's Ramsey.
"Most top players have one quality that stands out. You can't tell with Ramsey, he is not that quick, he is not Scholes for his football brain, or Roy Keane for his fight. But he is nine out of 10 in everything."
