Besiktas manager Slaven Bilic is hopeful his side can knock Arsenal out of the Champions League qualifiers, but knows it will not be easy.
The former Croatia boss, and ex-West Ham player, has identified the Gunners' key man - and it's in form Welshman Aaron Ramsey.
Bilic told The Sun: "Ramsey's not that quick, he's not Paul Scholes in his brain, he's not Dennis Bergkamp, he's not Mesut Ozil, he's not Roy Keane but he's got everything nine out of 10.
"He's the most important Arsenal player."
Ramsey began this season in the same style he ended the last, scoring a dramatic winner to send Arsenal fans wild, as the Gunners beat Crystal Palace 2-1 at The Emirates.
Arsenal have the first leg of their contest in Turkey, on Tuesday at 7.45pm, with former Chelsea striker Demba Ba the man to watch.
Bilic went onto make the bizarre admission: "In 10 games against Arsenal, probably we would lose eight, but I'm not saying we only have a 20 per cent chance."
He is clearly trying to put the pressure on the Gunners and hope his side's unity will see them through, but is under no illusions at how difficult it will be.
Stopping Ramsey will be key to that, but whether any side can do so at present, let alone Besiktas, is another matter.
