That's according to Okdiario's chief pundit Eduardo Inda, while speaking on El Chiringuito.
Inda says PSG chiefs rate Felix the best young player in Europe and intend to test Atletico's resolve with a major bid for the Portugal international in 2021.
He revealed, "It is a difficult operation to undertake.
"PSG would try to go after the most promising young man in Europe: Joao Félix.
"It is difficult to get him out of Atlético because he has a clause of €300m."
