Scottish teen Jack Harper is being tipped for greatness by Real Madrid coaching staff.
Real junior Harper, 14, is joining up with Ross Mathie's Scotland Under-15 squad for a two-day training camp next week.
Sanchez - who has brought through top Spanish stars like Juan Mata, Miguel Torres and Javier Garcia - has been wowed by highly-rated Harper since he joined from Andalucian boys club Los Boliches.
He told the Scottish Sun: "Time will tell how far Jack will go, but I think without doubt he is one of the hottest prospects to play for Real Madrid in the near future.
"He has a lot of talent and while he has a lot of developing to do, I really believe he will play for Real Madrid in years to come."
Highly-respected Sanchez refuses to compare Malaga-born Harper with any of the starlets he's worked with in the past.
Not because he doesn't want to heap pressure on the youngster - but because he reckons Harper is completely UNIQUE.
He claimed: "I don't want to compare Jack with anybody because he has a peculiar style of playing.
"He has an open-minded style with a mixture of the Scottish competitive mentality who is not scared of physical contact. In a way, Jack is unique."
