Manchester City are set to sign teenage Juventus forward Pablo Moreno in a swap deal which will see Felix Correia move in the opposite direction.
Goal can confirm that Spain Under-18 international Moreno is due to have a medical in Manchester on Monday ahead of signing a four-year contract.
He has, however, continued to impress in Turin and was expected to push for a place in Maurizio Sarri's first-team squad.
Former boss Massimiliano Allegri named the 18-year-old forward among the substitutes for a Serie A clash with Genoa last season, though that remains his only involvement with the senior team.
Moreno is now expected to complete his move to City this week, with Portugal U19 international Correia to depart for Turin.
Correia, 19, joined City from Sporting C.P. in 2019 and has spent the campaign on loan at Dutch club AZ Alkmaar.
Correia has made 23 appearances for AZ's U21 side, contributing three goals and five assists this season.
Moreno, who in April was named on Goal's NxGn list of the top 50 teenage footballers on the planet, could also potentially also go out on loan next season to gain playing experience.
Barca had wanted to keep the youngster, who can play anywhere across the forward line or as an attacking midfeilder, before his switch to Juventus in July 2018 in a deal worth a reported fee of approximately €700,000.
During his four years at La Masia he broke a number of goalscoring records. In his first season with the Alevin A, or U12s, he scored 72 goals in 27 matches. He backed that up with 41 goals the next year, 66 the year after that and a further 34 in what proved to be his final season with Barca.
So impressive were his performances that he earned a call-up to Spain's U16s squad at the age of just 14.
Meanwhile, Bulgaria U19 international Filip Krastev is also expected to join City from Slavia Sofia.
The Bulgarian side said in a statement that the 18-year-old agreed terms with City after passing a medical.
Krastev, 18, is expected to sent out on loan, with Belgian club Lommel - who were recently added to the City Football Group - a possible destination.
