Some Manchester City academy staff have reportedly unhappy the club avoided a transfer ban for breaking FIFA rules on signing young players.
City were found guilty of breaching regulations on the international transfer of under-18s in a number of cases which all occurred before December 2016.
City received a £315,000 fine from world football's governing body after the club "accepted its responsibility".
However, the Daily Mail reports that some staff in City's academy - considered one of the best in the country - feel that a transfer embargo would have provided the chance to help the development of younger players.
There was a belief that a ban would have required manager Pep Guardiola to follow the approach adopted by Chelsea manager Frank Lampard this season by giving more opportunities to some of the club's home-grown talents.
