Chelsea have signed Atletico Madrid and Spain midfielder Saul Niguez on loan with an option to buy.
The 26-year-old was a key player as Atletico won La Liga last term, making 33 appearances.
Chelsea doubted they could sign Saul, but managed to strike a deal, paying a loan fee with an option to make the move permanent.
Sevilla earlier confirmed that they had rejected Chelsea's "unsatisfactory" offer for France defender Jules Kounde.
The Spanish club stood firm over the fee required for Kounde, insisting he would not be allowed to join the Blues for less than his 80m euros release clause.
