Toni Rudiger says he'd welcome Kai Havertz to Real Madrid.
The Real defender's former Chelsea teammate is interesting the Spanish giants.
"I would be happy to play with him again at a club," Rudiger said of his Germany teammate. However it concerns the market, I have nothing to report to the club."
Rudiger made the same move a year ago.
Havertz has been told by Chelsea they will sell him if he doesn't sign a new contract.
