Diego Simeone discussed turning over an aging squad, saying that this summer is one of the most important he's faced since coming to Atletico Madrid.

"A renovation has been underway since last season when Fernando Torres, Gabi, now the likes of Juanfran who were references of the team and my guys who gave me everything, and did amazingly well. Now we are preparing the likes of Oblak, Saul, Gimenez to transition into becoming leaders," said Simeone.

Simeone also talked about the possibility of signing Joao Felix, saying that his move will force Atleti to update their style.

"If Joao Felix and others arrive with different characteristics to those who have been here before, then we will have to update ourselves," Simeone added.
