Nils Koppen has done 'nothing' to earn a promotion at Rangers, according to Kris Boyd.

The former Gers striker believes questions need to be asked over who made the decision to give the 39-year-old a more senior role as the club's new technical director.

Koppen joined the Scottish Premiership side last December as head of recruitment. 

Today, after just under a year in the post, he received a bump up to the position of technical director, meaning he'll take more authority over a variety of off-field issues at Ibrox.

Boyd clearly isn't convinced by that decision, as he called for a 'revamp' of the club's academy.

He told the Scottish Sun: "I don't know where to start. Who made the decision?

"There's no CEO. I just don't know - who's making the decisions? There's nobody above him.

"Why would you give someone a promotion when you don't have someone above them?

"What happens if you appoint a CEO and there are problems with Koppen and the CEO? I'm not saying that'll happen, but what if it does?

"They are important (bringing through more academy players and Scottish players). The other thing he touched on as well was getting more ex-players involved as well.

"I've got to be honest, I just feel as if it's what the fans are saying. I just feel it's what the fans are saying and it seems the right thing to say for Koppen.

"You only need to look on social media, this is not an appointment the fans are enamoured with. They're not looking at it saying 'we're absolutely delighted.

"You've got to earn the right to that promotion. There's nothing to suggest that Nils Koppen has earned this.

"He might be a good guy, you're telling me he's highly thought of behind the scenes. Right now the fans only see what has come through the door and its not been good enough. It's not been good enough.

"The recruitment is a million miles away from where it should be.

"You've got to remember as well, the things that were said in the remit back in the summer or even when Nils Koppen came in, they should be a guarantee.

"There should be a guarantee there are more Scots in that team, there should be players coming through the academy.

"That's not something that's new, because you're now in this role, you need to be seen saying the right things.

"That should just be a remit right from the football club. You're spending absolute bombs, fortunes on the youth academy."
