Southampton know the price Atletico Madrid want to sell Toby Alderweireld.
The Belgium defender is on-loan at Southampton from Atletico for the season, though no set price was agreed over a permanent deal.
However, The Sun says Atletico are willing to sell Alderweireld to Saints for €8.5 million.
The defender said last week: "I know Atletico decides, and that's normal.
"Then, of course, Southampton can have a say, and, at the end, it's my choice of course."
