Barcelona president Joan Laporta says signing permanently Joao Cancelo and Joao Felix will be up to sports director Deco.
Manchester City fullback Cancelo and Atletico Madrid attacker Joao Felix have impressed on-loan so far this season.
Laporta said on Cataluyna Radio: "If they continue playing like this, we will have to make an effort to sign them, but it all depends on what Deco says.
"The objective now is to win the League and fight for the Champions League as well as the Super Cup and the Cup.
"I have always liked Joao Flix, but also the other players on the team, which is now more valued in the market and more sustainable."
