Pochettino insists that playing crossbar challenge with Mudryk is key to building his confidence.
He said: "With Mudryk, I like to play sometimes to [hit] the crossbar from outside the box.
"He said to me, 'I don't want to play anymore with you because you always win.' I said 'yes, because I have the belief, and the balance between belief and quality I know very well because I'm 50 years old. You're still young and you need to know yourself'.
"Today [Tuesday] was the first day we draw, because I always won. Now you start to believe in yourself, believe in your quality. If not, it's difficult to balance belief and quality."
