Aro Muric will spend the 2020-21 season on loan at Girona.
The Kosovo international, who has made five first-team appearances for City, penned a new three-year contract extension last summer, taking him until to 2024.
He immediately joined Nottingham Forest on loan, where he made five appearances and will now continue his development with Girona.
Pablo Moreno,18, will join Muric in Spain.
He signed for City this summer from Juventus, where he has been part of the under-23 squad for the last two seasons.
Capable of playing anywhere across the front three and as an attacking midfielder, Moreno’s career began at Barcelona’s La Masia academy, where he broke several goalscoring records.
Everyone at City wishes Aro and Pablo the best of luck with their new adventure.
