Atletico Madrid coach Diego Simeone is a big fan of River Plate's young talent.
Simeone lavished praise on Víctor Camarasa, Matías Kranevitter and Emanuel Mammana, who are all being linked with Atletico.
"They are young footballers who play well, who are growing and developing in a very competitive league - one in which it's very difficult to make a name for yourself," said Simeone.
"I've know Mammana since he was a kid and we've been following Kranevitter since he joined River because my son also plays there; he's is a very good midfielder. Mammana's a full-back who is really progressing; both of them have a bright future ahead of them, I'm sure of that."
