German international defender Shkodran Mustafi has revealed Real Madrid have been in contact.
Whilst there is already a wealth of speculation Otamendi is a target for Real Madrid, they've also been linked with a move for Mustafi, which in comments to Sport 1 and via Mundo Deportivo, the player's father confirmed:
"It's true, there has already been contact about this. Real Madrid is a great club with a lot of success, and of course I would be lying if I said I wouldn't be proud if my son were to sign for this club." Kujtim Mustafi admitted with pride.
Speaking to the same broadcaster, the defender himself acknowledged the contact from from the Santiago Bernabeu, explaining: "At the moment I'm on holiday, but who wouldn't be delighted if Real Madrid were interested in them."
"It shows I've performed at a good level throughout the year. There isn't a player who wouldn't be happy." Added the German international.
The main obstacle for Real Madrid, as with any interest in Otamendi, is that Mustafi also has a €50 million clause valuation. Likewise, it's certain that Valencia wouldn't be willing to negotiate that figure, with La Liga rivals Real Madrid.
Given that Otamendi has already made it clear he wants to leave the Mestalla this summer, Valencia could now face a defensive crisis, if their other highly talented centre-back also has his sights set on moving elsewhere.
