Chelsea are in talks with Atletico Madrid on a season-long loan of Saul Niguez with an option to sign a permanent deal.
Manchester United have also remain interested in Saul but have not been able to reach an agreement with Atleti on a fee.
Saul, 26, has started both of Atletico\'s league games so far this season but has lost his status as a key player for coach Diego Simeone over the last year.
