Manchester City are close to signing Saul Niguez from Atletico Madrid for €80 million ($91 million).

Barcelona has also had interest in Saul, who was interested in joining the club before ultimately deciding upon City.

Pep Guardiola views Saul as the long-term replacement for Fernandinho.

"He can't stay at Atletico anymore, everything's complicated for him there," a source told ESPN FC.
