West Ham midfielder Manuel Lanzini was at the centre of Andre Villas-Boas' blow-up at Olympique Marseille.
The Sun says Villas-Boas quit Marseille after they decided against signing Lanzini on loan.
The former Chelsea and Spurs coach was keen on Lanzini, 27, as part of a major revamp.
He tried to swap him for Morgan Sanson and went back in with a loan offer at the death.
But Marseille went for Celtic's Olivier Ntcham instead and Villas-Boas walked.
