Former Barcelona striker Christophe Dugarry has questioned their swoop for Ajax midfielder Frenkie de Jong.

Dugarry rates the player, but the fee rising to €86m has stunned the French pundit.

Hinting at Financial Fair Play concerns, he said, "It's a defeat for PSG. This boy was wanted by the whole of Europe. He has a very interesting style but I do not hide that I ask myself questions when I see Barca buy players for 120-130 million each year with a huge payroll.

"We often bother PSG in these mercatos and we do not see them very active so the constraints are real but I do not see the side of Barça.

"I hope fairness is respected because it shocked me deeply."
