Tomáš Souček, Vladimír Coufal and Andriy Yarmolenko have all been called up by their countries for next month's FIFA World Cup qualifiers.
Following successful Euro 2020 campaigns for all three, their attentions will now switch to helping Czech Republic and Ukraine towards next winter's World Cup finals in Qatar.
Souček and Coufal both started every game as Czech Republic reached the quarter-finals of the Euros, eventually bowing out to Denmark, and will face three World Cup qualifiers over the next couple of weeks.
They currently sit second in Group E with four points from their first three games and first up is a home game against Belarus on Thursday 2 September, before they travel to Belgium three days later.
They end this international window by taking on Yarmolenko's Ukraine in a home friendly on Wednesday 8 September.
The Hammers' No7 meanwhile, who also reached the quarter-finals of Euro 2020, will be hoping to earn his 100th Ukraine cap when they kick-off their September fixtures with a World Cup qualifier on Wednesday in Kazakhstan.
A home meeting with France follows on Saturday 4 September, before that friendly in Czech Republic.
Ukraine are currently second in Group D, having drawn all three of their opening games.
