Atletico Madrid are eyeing Ajax defender Nicolas Tagliafico.
Marca says Tagliafico is on Los Rojiblancos' radar.
The Spanish club's transfers chief Andrea Berta has the Argentine's name top of his shopping list.
"If Diego Simeone is interested in me and really wants me then it means I'm doing well," the 26-year-old said.
"The important thing for now, though, is to think about Ajax.
"We're alive in three competitions and I need to focus on what's happening with the team in Holland."
