RIDVAN YILMAZ is a huge loss to Beskitas, admits boss Valerien Ismael.
The ex-West Brom manager didn't want to allow the left-back to join the Scottish giants.
The 21-year-old has been drafted into Ibrox as a quick replacement for Calvin Bassey who was sold to Ajax last week.
The deal is worth around £3million, with potential add-ons taking it close to the £5million mark.
He and Ben Davies have been signed by Giovanni van Bronckhorst as Rangers aim to reclaim the title from Celtic in the 2022/23 campaign.
Yilmaz said the move was a "dream come true".
However, his old boss Ismael did not share his views, as he warned he may not get the same attention from the Turkey national squad.
Ismael told Spor Haber : “We wanted to keep Rıdvan. I told him that with this fast-paced game (in Turkey), he could attract more attention at international level with the influence of his youth.
"Everyone is happy right now, probably only me may not be happy with the current situation. We are looking for players with the same quality who can fit into our system."
