Atletico Madrid are extremely eager to secure Chelsea wing-back Marcos Alonso.
The Spaniard could leave the Blues in the summer, when Ben Chilwell will be back to fitness.
According to Marca, Atleti coach Diego Simeone sees Alonso as his ideal left back.
Simeone would want Alonso to play as a wing back, with three central defenders and a right wing back alongside him in the defence.
Reinildo Mandava, who plays for Lille in Ligue 1, is another Atleti target for the same position.
