Former Rangers boss Stuart McCall has told BBC Sport that he thinks Gers defender Danny Wilson has improved in recent months, as seen by his performance against Celtic on Sunday.
Wilson, 24, actually started his career with Rangers, but having emerged as one of the top young players in Scotland, he was quickly snapped up by Premier League giants Liverpool.
A dismal spell in England led to Wilson returning north of the border, and after rebuilding his career with Hearts, the centre back surprisingly chose to drop down a division and re-sign for Rangers on a free-transfer last summer.
Wilson has formed a regular partnership with Rob Kiernan in the heart of the Rangers defence, but fans have largely been split on his performances this season, with the Gers having some shaky games defensively over the course of the campaign.
On Sunday, the unheralded Wilson played in his biggest game since returning to Rangers, as he started in the Scottish Cup semi-final against Celtic - and he played a huge part in Rangers' win, earning praise from the club's former manager Stuart McCall.
McCall, who was replaced by Mark Warburton last summer, covered the game for BBC Sport, and awarded Wilson a mark of eight out of ten for his performance against Celtic.
McCall added that he feels Wilson has improved in recent months, and he showed what he can do against Celtic by shackling Celtic goal machine Leigh Griffiths for 120 minutes.
"Has improved in recent months and that showed in this game," said McCall. "He took charge at the back and showed maturity and composure throughout. Handled the difficult challenge of facing Griffiths well," he added.
