The 25 players with a star by their name are 21 or under and have played for West Ham for two years or more so do not need to be registered in the primary 25 man squad A list. Europa allows an unlimited number of young players on the B list.
The 25 man A list squad needed to be registered with UEFA by 23rd June for the first qualifying round. West Ham have until 11th July to register further players for the second qualifying round. The club is also allowed to introduce one additional player to the A list up to 24 hours before kick off so Payet could still be a late addition to the squad.
