Chelsea and Atletico Madrid are chasing Atlanta United midfielder Thiago Almada.
The Argentina international international is ready to leave the MLS club this summer.
AS says his deal carries a 27m buyout clause - which is around double what Atlanta paid Velez Sarsfield for Almada two years ago.
Atletico see Almada as a replacement for Angel Correa, with Chelsea also interested.
Botafogo are also keen, but Almada wants to continue his career in Europe.
