Spurs are set to land a huge transfer fee of over £80m if he does go - and ex-England international Scales believes the sale of their prized asset is not a bad thing.
He told the Daily Star: "It's not all doom and gloom. Spurs have got themselves an incredible deal on the table.
"It's pretty clear they have made a world-record bid - or are preparing to. Real Madrid could put a couple of players in it too. Fabio Coentrao and Angel di Maria might be part of it.
"They would both be quality additions to the squad. Spurs would still have money to buy more, too.
"It's a chance for the club to take the next step and push on and become a top-four side."
