Pochettino insists the speculation over his future will not affect the teenage sensation when Saints take on Premier League leaders Arsenal tonight.
Pochettino said: "He is dealing with the media attention very well. When he got here he was a kid, now he is a man.
"These things do not affect him at all. He hasn't said anything to me that has changed the situation from when he said he wanted to stay. It is still the same."
