Benfica sports chief Rui Costa recognises Joao Felix and Ruben Dias are two of the most wanted young players in Europe.

Joao is being linked with Manchester United and Manchester City, while Dias has been linked with Liverpool.

Rui Costa says of Joao: "Someone called him my heir. Or the new Kaká. The truth is that Felix is Felix alone. He has an outstanding feel for the game and he has a rare ability, he can guess what will happen before goals. He is a midfielder, a trailing striker with a remarkable sense of goal, he has scored ten goals in the league.

"A €120m buy-out clause? We will try to keep him as long as possible, for Felix and all other players. It is the club's policy, but we are aware that the clauses exist and some players cannot be held in Portugal."

On Dias, he also told Tuttosport: "I don't know if he will leave. We still want to keep him and Ruben knows that he has a lot of love here. The club needs to sell to make money. We will see how the summer market is developing."
