Mourinho compares Tottenham teenager to Marcus Rashford

The 16-year-old made his fourth senior appearance for the club on Wednesday, coming off the bench for the final 10 minutes a 4-0 win over Wolfsberger.

And he made a telling impact almost immediately, hustling a defender out of possession to set up Carlos Vinicius for the hosts' fourth goal.

Mourinho could barely contain his delight at the rapid progress of a player whose quality reminds him of another major talent he once helped develop.

"He is a diamond, a kid with incredible potential," the Portuguese told BT Sport.

"He has worked many times with the first team and that gives him a different personality. He is still 16, 17 soon [in March] and I believe next season he will be a first-team squad player because he has a lot of talent.
