The crowd went wild as players surrounded the World Cup victor, but one fan, who was named after the great George Best was celebrating more than most.
"If you're not happy, you can not give your best", Pogba said.
"I always give my best for the fans, for the team mates. and for the people that trust me".
Just 26 days after lifting the World Cup with France, the 25-year-old scored an early penalty and dominated the midfield before being replaced after 84 minutes. I am the same.
The Ghanaian defender's hand had a touch of the ball with just three minutes into the start of the game and Paul Pogba struck the first goal of the season from the resultant free kick. They spent more money than us, so in the Premier League we must get used to teams with players of the same quality that we have.
United would be absolutely mad to let Pogba leave now that the transfer window in the Premier League has closed and they can not replace him until January.
Pogba joined United from Juventus for a then-world record £89m in August 2016.
The Frenchman believes that there is no point doing a job if you are not enjoying it, so he was asked whether he is currently happy and comfortable right now.
United have never had a director of football before but it's a role that has worked quite well for arch-rivals Manchester City, who appointed Txiki Begiristain in 2012 to much acclaim.
Pogba said "everybody was on the same page" in the France dressing room, from manager Didier Deschamps to the staff and players. "It's going to be easier and it makes the team go higher".
Considering Jose Mourinho appeared to be engaging in a policy of calculated moroseness during pre-season, his first team sheet of the season was decorated in olive branches. I always love the club.
This put them in a comfortable position throughout the rest of the match, and even more so when Luke Shaw tapped home in an unorthodox manner in the second half. I want to play for England and I want to be involved again.
"I won't be full from a World Cup", Pogba told Sky Sports.
