During the international break, five of West Ham’s youngsters were involved in action.
With Marko Arnautovic, Lukasz Fabianski, Robert Snodgrass and Andriy Yarmolenko representing the Hammers at senior level, five more players played youth internationals.
Among these were Irish duo Josh Cullen and Conor Coventry, as well as English pair Nathan Trott and Ajibola Alese.
Sebastian Nebyla was involved for Slovakia. Here, we look at each player and how they did over the break.
Cullen captained Republic of Ireland’s under-21 team but suffered a disappointing result.
In their first game, the boys in green were held to a 1-1 draw with Kosovo. But they eyed redemption against Germany in Dublin.
Cullen, who is on loan at League One side Charlton Athletic, led his side out but was unable to prevent a 6-0 loss.
Schalke duo Cedric Teuchert and Suat Serdar scored five between them. Teuchert scored a hat-trick and Serdar grabbed a brace after Mainz’s Aaron Seydel gave Germany an early lead.
Trott missed out on England under-20’s win over Switzerland, but was selected for their second match.
Playing his fifth game for the under-20 side, the 19-year-old was unable to prevent a 3-1 loss against Netherlands in Katwijk.
Coventry represented Republic of Ireland’s under-19 side in a double header against Wales.
Wales won the first game 1-0 before the Irish claimed a 2-0 win two days later. Coventry played in the first game, which ended in defeat.
Academy defender Alese picked up some silverware during the international break.
Playing in the Limoges tournament in France, England under-18s ran out winners after the three-game competition was completed.
Alese was a late substitute in the 3-0 victory over Netherlands but followed that up with 90 minutes and a clean sheet in the 3-0 win against Russia.
The 17-year-old also played 90 minutes against the hosts France in the final game, helping England to a 2-1 win.
Nebyla was representing Slovakia’s under-17 side and he was a substitute in a 1-0 win over Sweden.
West Ham have two young players out on loan who were included in their respective national squads this week.
Sead Haksabanovic, on loan at Malaga, was named in Montenegro’s squad. The 19-year-old did not feature in either game, though.
Edimilson Fernandes was also selected for national duty. The Switzerland international, on loan at Fiorentina, played just less than 30 minutes against England in a 1-0 friendly loss.
