The goalkeeper joined Spurs from Burnley this summer.
On Mourinho, he told BBC Sport: "Jose is very clever at how he works the media. He is a different guy in his own environment, with his own players. He asks you to give your best and show your quality. That is how I work.
"I don't claim to be the most talented guy in the world but I will give it everything.
"Trust works both ways. He definitely gives that and I enjoy working with him."
