So he opted to forfeit a summer break and make himself available to represent Uruguay, the home country of his football legend dad Gus, in the FIFA U-20 World Cup in New Zealand.
It means Poyet will get some much-needed experience and game time ahead of a crucial season back at Upton Park where the Hammers could have as many as 23 extra matches to contend with due to their involvement in the Europa League.
And things have started well on the other side of the world for a player who will be hoping to force his way into the new manager's plans after he was brought on to help see out a hard-fought 1-0 win over Serbia on Monday.
The midfielder appeared as a 71st-minute substitute as Uruguay beat their European opponents at the Forsyth Barr Stadium in Dunedin, New Zealand, as reported by West Ham's official website.
Uruguay’s goal was scored by Facundo Castro 11 minutes after half-time, with Poyet helping to ensure the 2013 runners-up made the perfect start to this year’s finals.
Poyet will now face Mexico on Wednesday at 5am UK time before completing the group stages by tackling Mali at the Waikato Stadium in Hamilton on Saturday.
The highly-rated star will not be the only Hammer appearing on the international stage this summer, though.
The club's Ecuadorian striker Enner Valencia will step up preparations for this month’s Copa America finals in Chile by facing Panama in a pair of warm-up fixtures on Wednesday and Saturday respectively.
