Those appear to have been dealt with, as L'Equipe report today that they have now secured a work-permit for Onyekuru and he has agreed on a five-year contract with the Ligue 1 side.
The latter thanks AS Monaco for giving him the opportunity to discover the French championship and wishes the Club and supporters a great season 2019/2020. "I look forward to meeting my teammates", the 22-year-old told Monaco's website.
Onyekuru scored 16 goals in 44 appearances last season, helping Galatasaray retain their Turkish Super Lig title by a two-point margin from city rivals Istanbul Basaksehir.
He won 14 caps for Nigeria and played in the 1994 FIFA World Cup, missing the first game through injury but then played against Argentina and Greece before Nigeria were knocked out by Italy.
However former club captain Radamel Falcao and Portugal wide-man Rony Lopes have been linked with moves away from the Principality.
At Monaco, he will replace Belgian global Nacer Chadli who has gone on loan to Anderlecht.
By mutual agreement, AS Monaco and Michael Emenalo decide to put an end to their collaboration.
