Atletico Madrid coach Diego Simeone has taken fresh aim at Joao Felix after defeat to Barcelona yesterday.
Simeone used Pablo Barrios as an example of the work he wants from his players, in a reference to Felix.
He said, "The reality is that we lost and it is true that the team made merits to be able to take another result.
"Areas continue to be decisive in football. Today I am leaving with the feeling that we did more good than bad things and we are going to compete.
"We knew that Barrios might not have a great game, but investing in footballers like him has good consequences in the future. He has to learn to play against better rivals and this match is the one that will let him the most to grow.
"He is noble, works hard, grows, and does not think individually like others."
