The Nigeria international missed the Stamford Bridge outfit’s warm-up game against Perth Glory following his participation at the 2018 World Cup.
However, Moses made a return to the side as a substitute - playing as a winger in Maurizio Sarri's preferred 4-3-3 setup - after replacing Pedro and converted one of the kicks that helped the Blues defeat resilient Inter 5-4 on penalties after the regular time ended in a 1-1 stalemate.
The former Wigan Athletic man then took to the social media to share his feeling on rejoining his teammates on the pitch.
“Great to be back out there with the boys,” Moses posted on Instagram.
The versatile player will be expected to play a part when Chelsea clash with Arsenal in their next game in the competition on Wednesday.
