Conor Gallagher's potential transfer from Chelsea to Atletico Madrid remains uncertain due to financial complications and failed transfers. The issue stems from Atletico needing to sell players, such as Samu Omorodion or Joao Felix, to fund Gallagher's move. Gallagher, who has been in Madrid for five days, is now back in London for training while Chelsea and Atletico continue negotiations. Chelsea had agreed on a £33.7 million deal for Gallagher, but Atletico's inability to finalize the necessary sales has stalled the transfer. Both clubs are exploring alternative deals, including a possible return of Joao Felix to Chelsea, but a final agreement has yet to be reached.
