Jose Mourinho believes Atletico Madrid signing Joao Felix must learn to handle his price-tag.

Felix arrived this summer from Benfica for €120m.

"He has a challenge due to the extent of his talent and because of the investment the club have made on him", Mourinho told the Portuguese Football Association's television channel.

"I believe that he can't escape this responsibility. It doesn't matter if he's 18, 20 or 25.

"What matters is his talent and the responsibility he has."
