Declan Rice and Gabriel Magalhães trained with Arsenal ahead of their Champions League trip to face Sporting CP in Lisbon.
Rice had pulled out of the England squad with a fitness issue, while Gabriel picked up a knee knock in the FA Cup defeat to Southampton, but both returned to training before the match.
Leandro Trossard also trained, but Bukayo Saka was absent after leaving England camp early.
Arsenal will be hoping to avoid a third straight loss as they prepare for the quarter-final clash.
