Atletico Madrid will allow midfielder Saul Niguez to decide his next destination as both Chelsea and Manchester United vie for his signature.
Saul has been told that he is free to leave the club this summer and had initially been keen to join Barcelona, but talks over a swap deal involving Antoine Griezmann broke down and allowed suitors from the Premier League to step in.
Atleti's hopes of a permanent transfer soon faded and a loan move is now the likeliest outcome for Saul, whose representatives have spoken at length with both Chelsea and United in recent days over a possible move.
As noted by Fabrizio Romano, Chelsea have now lodged an official bid to sign Saul on loan with an option to buy, while United have also stepped up their interest in the past 24 hours.
As far as Atletico are concerned, sources have confirmed to 90min that Saul will be given the final say on his future, and Los Rojiblancos are prepared to do business with whichever team can convince Saul to join.
The 26-year-old is keen on a move to the Premier League and is now taking time to decide which club to join, with the offer of regular playing time understood to be a decisive factor.
Chelsea boss Thomas Tuchel is keen to find a fourth midfielder to use in his regular rotation alongside N'Golo Kante, Mateo Kovacic and Jorginho, and the opportunity to sign Saul on loan is one which the board at Stamford Bridge have deemed too good to pass up.
The Blues also remain interested in Sevilla centre-back Jules Kounde and are hopeful that an agreement can be reached soon - a process which would be aided by the potential departure of Kurt Zouma to West Ham United.
Chelsea will continue to try and convince Saul to head to Stamford Bridge, but United are expected to follow up on their interest and force the midfielder into a decision.
