The Frenchman has made a sensational start to life at West Ham and his team-mates will be relying on him to keep it up.
With most of the Premier League, it would be easy to pick a left-field choice as a man who could make the difference over the coming weeks.
Indeed, the Frenchman is and will continue to be the east London club's talisman after the international break.
Such is the standard of the Frenchman's form, a lot of West Ham's momentum now rests on his shoulders.
If the hub of the Hammers' creativity falters, it will likely have repercussions throughout Slaven Bilic's side as a whole.
But the 28-year-old has shown no signs of slowing down, of course, and will be revitalised after genuinely getting a break during the internationals (he wasn't picked for France).
That's why Payet will continue to be West Ham's most vital asset. At Crystal Palace next weekend, Bilic will need the playmaker at his most influential on the counter-attack.
He'll then have to prove his worth against Chelsea, before traveling to Watford to help break down the Hornets' back four.
Victor Moses, Manuel Lanzini and more - perhaps Michail Antonio now, too - will all be key. But Payet will remain West Ham's linchpin.
