The Argentina international remains at the centre of a transfer storm ahead of the final days of the summer window after declaring his desire to leave Madrid during the 2026 FIFA World Cup.
Atletico club president Enrique Cerezo has previously confirmed Barcelona have not been 'up to the job' of making a suitable offer and completing a transfer for the former Manchester City striker.
Arsenal are still in the running to wrap up a deal, but time is running out, as both Diego Simeone and Cerezo look to keep him in the Spanish capital.
Alvarez was given a mixed reception after coming off the bench in last weekend's 2-2 home LaLiga draw with Villarreal and the club opted against him applauding the Atleti fans at full-time.
The 26-year-old missed today's training session due to illness and Simeone insisted the situation remans unchanged.
