Atletico Madrid coach Diego Simeone has spoken highly of Mauricio Pellegrino's Leganes.
Los Rojiblancos will face Leganes on Saturday.
"I like Leganes and Pellegrino's work is fantastic, as he had already done well in other teams," said Simeone.
"Once again he has managed to generate a commitment among his players, who play the way that is best for the team.
"The absences of Filipe Luis and Lucas Hernandez are important, but we will can use Andres Solano or Saul Niguez in their left-back position, or play with a back five."
