Atletico Madrid are preparing a major clearout this summer.
On Tuesday, Atletico were eliminated from the Champions League by Borussia Dortmund at the quarter-final stage.
Relevo says the club wants to refresh the squad and so plans to sell six players this summer.
Memphis Depay, Angel Correa, Saúl ÑÍguez, Mario Hermoso, Stefan Savic and Gabriel Paulista could all be on their way out of Atlético.
Hermoso has previously been linked with Real Madrid, Barcelona and Inter. The centre-back has a contract that expires this summer.
Former Arsenal player Gabriel Paulista is also on an expiring contract. The centre-back joined Atlético Madrid as a Bosman in January.
Midfielder colleague Stefan Savic had his contract automatically extended this season. The deal runs to the summer of 2026.
The attacking pair Memphis Depay and Angel Correa can also be sold.
Saúl ÑÍguez, had an unsuccessful loan spell at Chelsea and was linked with the Saudi Pro League last summer. Despite the fact that his form has improved this season, a move again seems likely.
