Al Nassr star Cristiano Ronaldo is full of praise for Portugal teammate Joao Felix.

The Atletico Madrid striker is being linked with Newcastle and Aston Villa after a six month spell with Chelsea.

"Can he [Felix] repeat my successes in Spain? I believe that a lot because he is an excellent player with a lot of potential who can evolve," he told Mundo Deportivo.

"You can see the same with Bernardo [Silva], although he is already much more mature in this regard. It is difficult to make calculations in current football.

"You bet a lot on the potential, and the football industry is different. Leaving aside the case of Joao Felix, any player is worth £90m, even without having proven anything.

"There is more money in football. A central defender and a goalkeeper can be worth £60m to £70m. I don't agree, but this is the world we live in, and we have to respect it."
