Atletico Madrid they are approaching a crunch a few days into their search Chelsea star Conor Gallagher.
The England international is back in London as talks stalled in the Spanish capital, and will not fly until firm progress is made.
Los Rojiblancos are preparing a new round of talks with the potential of Joao Felix being included in a swap to take Gallagher to the Spanish capital.
However, there remains the possibility of formulating a Plan B, and Atletico Madrid could renew their interest Valencia star Javi Guerra.
Valencia sporting director Miguel Angel Corona previously claimed Atletico Madrid had pulled out of a deal to sign Guerra earlier this month to focus on Gallagher.
According to a report from The AthleticThere are no set plans to watch Guerra again, but it's still on the radar if Gallagher stays.
Gallagher has only trained since his return to Chelsea, with the Blues open to selling, and his place at Stamford Bridge is uncertain if a transfer collapses.
