West Ham have rejected a second bid from Marseille for France forward Dimitri Payet.
The improved offer from the Ligue 1 side – reported to be £1m higher than an initial £19m bid – was turned down by Hammers chairman David Sullivan.
He is said to be taking a tough stance and refusing to be bullied into a quick sale, with the club having no financial need to sell.
Manager Slaven Bilic says Payet, 29, no longer wants to play for the club.
Payet is not training with the first team and will continue to work with the under-23s.
The Premier League club said they would prefer Payet to apologise to supporters and return to first-team training.
