Lisandro Martinez allegedly laid a foul-mouthed outburst at Ajax techical director Gerry Hamstra to try and force through his move to Manchester United.
Earlier this year, Martinez joined the Red Devils in a £55m move - but not without throwing a tantrum, and calling Hamstra a 'f****** nobody'.
It is not the only time players have revolted to try and get away from the Johan Cruyff Arena this summer, with Antony going on strike ahead of his own big money move to United, and Mohammed Kudus reportedly refusing to train with Ajax in a bid to force a move to Everton.
