The Frenchman has left the club after falling out of favour with Slaven Bilic.
The club confirmed yesterday – via its official site – that the French midfielder had agreed to leave by mutual consent and Gold addressed his departure last night.
The former West Brom midfielder failed to convince Slaven Bilic he could play a role this season and is believed to have had a training ground fallout with the Croat.
Bilic gave the 30-year old the chance to impress early on and he featured in four Europa League qualifying games before a breach of discipline in August saw his relationship with the manager sour, according to ESPN.
Amalfitano joined the Hammers from Marseille on a one-year deal last summer, after impressing during a season long-loan with West Brom, and his contract was extended by another two years in March.
Despite the award of a new deal, the Frenchman struggled to replicate the form he had shown at the Hawthorns the previous season and his days became numbered after the arrival of Bilic.
