The Premier League club has been negotiating with the Columbian club and is about to sign their forward Marlos Moreno.
The 19-year-old has been heavily linked with a move to City. The club is supposed to pay £4.75m for the youngster.
Marlos Moreno could probably join Deportivo La Coruna, as soon as the signing has been completed.
He would be the club's third signing for this week after Leroy Sane and Gabriel Jesus.
Pep Guardiola mentioned that he's keen to sign highly-rated youngsters for the Premier League club.
