Dimitri Payet is set to start his first match of the season when West Ham face Watford on Saturday.
The France midfielder was one of the stars of Euro 2016 but has made just one appearance from the substitutes' bench for the Hammers so far due to a thigh problem.
But Payet, who hit 12 goals last term, has proved his fitness with two substitute appearances for his national side and is poised to go straight back into the starting line-up against the Hornets.
"He hasn't played for us, apart from as a substitute against Chelsea, but he played 45 minutes for France against Italy, and then 35 minutes against Belarus," said Hammers manager Slaven Bilic.
