Charlie Nicholas reckons Rangers will need to bring in as many as EIGHT signings this summer.
And he believes Calvin Bassey is the man who will fund Giovanni van Bronckhorst's rebuild.
The versatile Ibrox defender has added to his growing reputation after a stunning performance in the Europa League final defeat to Frankfurt in Seville last week and the Scottish Cup win over Hearts at Hampden.

Big decisions will need to be made at Ibrox this summer with Nicholas putting Bassey's minimum value at a whopping £25million.
Aston Villa has been credited with an interest in the Rangers star, who ex-Celtic man Nicholas reckons is already a better player than England international Tyrone Mings.
Writing in his Scottish Daily Express column, he said: "I can see Rangers getting £25 million if they sell Calvin Bassey to fund their summer rebuild.
"You can see why Steven Gerrard at Aston Villa are so keen to get him but there will be a string of top clubs looking at him.
"I think the minimum value would be in the £25 million bracket.
"The reason why I put him in that range is because he is already a better player than Tyrone Mings.
"He was one that was built up and has ended up becoming an England international but I look at Bassey and I think there is more.
"I also think he has more potential to get even better. I have heard people in recent weeks say how good he has been but he has been like that for the last four or five months.
"For me, he has been the best young player in Scotland.
"The one player that the top English and European clubs will be looking at is absolutely Bassey.
"How Leicester City didn’t see the potential in him is really surprising.
"I would be simply amazed if Bassey was still at Ibrox next season."
It's set to be a big summer of transfer activity for Rangers and boss Giovanni van Bronckhorst and Nicholas reckons it will take as many as EIGHT new summer additions at Ibrox.

John Souttar is on the way in after penning a pre-contract deal from Hearts.
But Connor Goldson is set to leave on a free while the futures of the likes of Steven Davis, Allan McGregor and Leon Balogun are up in the air with the trio out of contract.
A number of key players like Alfredo Morelos, Ryan Kent and Joe Aribo are entering the final year of their current deals and big decisions will also need to be made if extensions can't be agreed.
He added: "I think van Bronckhorst has an enormous rebuild this summer.
"I would expect Ross Wilson and his team will be on the road on that front.
"As I have said, they will definitely be looking for a goalkeeper.
"With Connor Goldson away, Bassey away. I don’t think Leon Balogun is good enough and I also think Borna Barasic will be on his way.
"They could need four or five defenders they will need to bring in because so far it is only John Souttar they have lined up to come in.
"The midfield is quite strong.
"Steven Davis is out of contract but I would give him another year.
"Aaron Ramsey will move on and Amad Dallo has been a waste of time and upfront they have significant problems even when Alfredo Morelos is fit.
"I think Giovanni has the best part of eight players to find."
