The former Spurs star and manager said on TNT: "He has a little bit of everything. He has been thrown into games but mentally he has done it, that is the most important thing for me. Has more than done it! He will only grow and grow.

"He has learned so quickly. Some people take two seasons to grow and develop.

"He's improved in such a short time. What he's going to be like when he's 23, 24 is going to be scary. He's earned the right (to be in the starting eleven) based on the performances he's delivered. Mentally he's got it, you can see it."
