Besiktas had a breakthrough in their bid to sign Arsenal keeper David Ospina today after reaching an agreement with the player.
A source close to Besiktas revealed to Turkish-Football that personal terms with Ospina have been agreed.
The Colombia international is keen on making the move after agreeing to lower his £3.65m per-season wage demands.
The prospect of being a first-team player on a long-term deal proved an attractive proposition for Ospina.
Besiktas have yet to strike a deal with Arsenal over the transfer arrangement.
The Black Eagles have two offers on the table, a loan move with a buyout clause option or a permanent deal.
The Gunners are not keen on a loan and would prefer to sell.
Besiktas want Arsenal to reduce their asking price which is currently in the region of £5m.
We reported yesterday that club president Fikret Orman and the transfer committee are in London.
The primary aim of the traveling party was to sell Domagoj Vida but time is running out on finding a buyer before the transfer window shuts at 17:00 GMT.
The Black Eagles do however, have until the end of the month to sign Ospina as the Super Lig window ends on 31 August.
The Besiktas delegation are currently locked in talks and want to return with the keeper.
Ospina represented Colombia at the World Cup and played as first-choice keeper in cup competitions for the Gunners last term however, he has now third in the pecking order behind Bernd Leno and Petr Cech.
The Super Lig outfit are also considering their options with regards to Danny Welbeck after being informed Arsenal are prepared to part ways with the striker as well this summer.
