The Kosova Albanian midfielder has broken into the City first team this season under Manuel Pellegrini and will continue his development under incoming coach Pep Guardiola. Celina has agreed a deal until the end of the 2019-20 season worth roughly £12,000 per week. Guardiola will assess him in pre-season before deciding whether he will be loaned out next season.
Celina, who turns 20 in September, grew up in Norway but decided to represent Kosovo at international level. He will play for them in 2018 World Cup qualifiers starting in September.
