Moses has been on holidays since the Super Eagles of Nigeria exited the 2018 World Cup in the group stage.
The 27-year-old played all three of Nigeria’s games at the World Cup in Russia.
Due to his World Cup engagement, the Nigeria international resumed late for pre-season and missed out on Chelsea’s pre-season trip to Australia.
Moses took to his to share a photo of him with Antonio Rüdiger and Willy Caballero who also returned for preseason after their World Cup campaigns with Germany and Argentina respectively.
“Good to be back with the lads today,” Moses wrote alongside the photo.
In their absence, Chelsea will face Perth Glory on Monday, July 23 in Perth.
