London's "Chelsea" team is fed up with the active actions of Munich's "Bayern" management.
As reported by the website "Goal", the English are preparing to complain to FIFA about the Bundesliga champions, suspecting that the acceptable limits were exceeded in enticing young forward Callum Hudson-Odoi.
It was reported earlier that "Bayern" made a fourth offer, worth about £35 million, for the 18-year-old talent.
Chelsea believes that the Munich team conducted improper negotiations with the player.
The current forward's contract with the English team will expire in the summer of 2020.
