The agent of Toni Kroos says Real Madrid president Florentino Perez can be proud of his deal for the German.

Volker Struth is amazed Real managed to sign the German midfielder three years ago from Bayern Munich.

"Toni was dissatisfied with Bayern's offer to extend," he recalled to BILD.

"That is why the negotiations were quickly frozen.

"If you look at the prices today and you have the spirit that Toni (Kroos) signed for Real Madrid for 25 million euros, you can say that it is best piece of business of the century for Real."
