Allan McGregor could refuse the chance to link up with Besiktas.
The Scotland international is one of several players to have left Rangers in recent weeks, following their demotion to the Third Division.
McGregor, rated as one of the best goalkeepers in Britain, has signed a two-year deal with Besiktas, admitting he couldn’t refuse the Turkish giants.
“It's a big club, with a big tradition,” he told BJK TV. "Supposedly, they have great fans and a lot of noise in the stadium so I'm very excited.”
