Michael Hector has committed his future to Reading after signing a new three-year contract with the Championship club.
Watford have confirmed the signing of Austria defender Sebastian Prodl from Werder Bremen.
The 29-year-old reportedly had a training ground bust-up with Marseille coach Marcelo Bielsa and is keen to exit the club.
And Amalfitano is prepared to go on strike to ensure he returns to the Premier League with the Hammers before the closure of the transfer window at the end of this month.
Amalfitano, who has one international cap for France, was on loan in England with West Brom last season.
During his time at The Hawthorns, Amalfitano scored four goals in 28 appearances for Albion.
Amalfitano started his career in France with Sedan and spent three years at Lorient before moving to Marseille in 2011.
