Antony was photographed strolling back to his Manchester hotel on Sunday evening having been out to enjoy a celebratory dinner with friends.
The Brazilian, who joined the club from Ajax last week in a deal worth £85.5m, scored on his debut as United extended their winning run in the league to four games with victory over leaders Arsenal.
Clearly having enjoyed his first taste of life as a United player in front of a raucous Old Trafford, Antony was snapped returning from dinner at the Hawksmoor steakhouse in Manchester.
Having just arrived at the club, Antony is currently staying at The Lowry hotel, infamous for being Jose Mourinho's residence during his stint as United boss.
