Benfica president Luis Felipe Vieira has revealed that the club are looking to increase the release clause of youngster Joao Felix.
The 19-year-old has enjoyed an excellent breakthrough campaign, with 10 goals and four assists coming from 18 outings in Portugal's top flight.
The likes of Liverpool, Manchester United, Real Madrid and Juventus have all been linked with an approach for the playmaker, but Vieira has indicated that the prospect will not move to another team during the summer.
Vieira told Tuttosport: "I am happy that all of Europe is talking about Benfica's talents. Now it is clear that our project of betting on young players is bearing the desired results.
"Joao Felix the next Ronaldo? There is only one sure thing: Felix is one of the best talents produced by Portuguese footballer since Ronaldo. Juventus' and Real Madrid's interest in him? Ask them.
"At this moment we are not interested in selling him and soon we will increase the release clause in his contract."
Felix's release clause already stands at €120m (£102.83m).
