Chelsea will report Bayern Munich to FIFA if they find evidence that the Bundesliga champions have been 'tapping up' Callum Hudson-Odoi, Goal can confirm.
As reported by Goal, the Bundesliga giants have tabled a fourth bid worth £35 million ($45m) for the 18-year-old winger, while they have offered him the No.10 shirt in an attempt to convince him to move to Germany.
But the Blues will act should they find that Bayern made any illegal approach to Hudson-Odoi.
'Tapping up' in football describes the illegal practice of clubs bending the rules to sign a player, which includes contacting the player, family or their representatives without the permission of the club holding their registration.
