Clubs across Europe are on high alert with Yannick Carrasco facing being squeezed out of Atletico Madrid in January.
The Belgium international has clashed with teammates and been jeered by fans in recent weeks.
AS says a locker room row involving club favourite Gabi saw teammates having to pull the two men away from eachother, while the Belgian was booed by Atletico fans for his strop at being substituted during their Champions League meeting with Qarabag.
The winger is admired by Chelsea boss Antonio Conte, while he was also been linked with Manchester United and Tottenham over the summer.
Plans to renew Carrasco's contract this season have been delayed and with Vitolo due to arrive in January after his spell with Las Palmas, a winter sale is now being actively discussed inside the Metropolitano.
