He said: "He asked me [about Tottenham]. When the deal was done, he texted me and told me how great the training ground was. He was very excited. I wish Mathys all the best. Hopefully he gets a lot of playing time. That's what he needs. He needs to develop and experience the highs and lows on the pitch. I know Tottenham well, they will look after him well. Hopefully he does well there. He should show what he can do at the highest level."
