The Manchester City and England winter hasn't had the best of seasons with Jeremy Doku taking his place in the team, but he was still able to enjoy himself back in the first team.
Left out against Bournemouth as Doku ran wild with a goal and four assists, Grealish was back in action against Young Boys in the Champions League as the holders looked to wrap up their rather easy Group G.
Having comfortably beaten the Swiss side 3-1 away in Bern, they were welcomed to the Etihad for the return fixture, but their travelling supporters didn't look too pleased.
Dressed in bin bag-like waterproof ponchos, the Young Boys fans were seen dishing it out to Grealish with every possible offensive hand gesture available to them.
The no.10 didn't mind, though, looking up gleefully from the pitch as the abuse rained down along with the Manchester weather.

Young Boys fans may have been better advised to show some respect for Grealish, given what can happen when you do.
A fan favourite for both City and England, in October Grealish was part of the side that lost 1-0 in a huge Premier League defeat to Arsenal.
Despite the disappointment of giving up ground in the title race, Grealish still had time to leave a young Gunner absolutely buzzing.
The 28-year-old clambered into the crowd after the defeat to take pictures with some young fans, and even gave one his shirt.
