Chelsea and Atletico Madrid have agreed a Deadline Day deal for Saul Niguez to join the European champions on an initial loan deal with an option to buy.
Chelsea will pay a £3.4m (€4m) loan fee and will have the option to buy the Spain international for £30m (€35m) next summer.
Saul, who is keen to make the move to the Premier League, will not be flying to London on Tuesday night.
The 26-year-old was part of Diego Simeone’s title-winning side last season and has made more than 300 appearances for Atletico since breaking into the first team as a 17-year-old in 2012.
He has previously been linked with a move to the Premier League, with reports intensifying this summer that Manchester United would rival Chelsea for his signature.
