Showing few signs of rust despite only returning to training this week, the World Cup victor, wearing the captain's armband, impressed in possession and without it, leading by example and keeping his cool from the spot.
Pogba endured a turbulent season at Old Trafford last term and was dropped for a crucial Champions League tie with Sevilla in favour of 21-year-old Scott McTominay.
A tense relationship with Jose Mourinho appears to be at the heart of it. Questions about their relationship were raised last term and the midfielder is said to have been annoyed by his manager's comments around the World Cup. "It's a different team, obviously". I think one defensive mistake and probably the linesman could help him and give a free-kick against Leicester. Leicester got off to a poor start to the season but were able to climb the table throughout the season, finishing ninth.
"I had only two options: Scott [McTominay] or Paul, but if I play Scott I play two kids and a new player, so I asked Paul and he put himself available for the team and he was very, very good for us".
There seemed to be an argument between Pogba and Alexis Sanchez over taking the penalty but the captain soon stepped forward and took his own sweet time to beat Kasper Schmeichel.
"I know that Paul doesn't resist for 90, the same with Fred".
"We don't really have one", Pogba said on Sky Sports.
"I think Mr [Richard] Scudamore must be happy because it's a good way to start the Premier League".
Sharing a picture of his goal celebration on both Twitter and Instagram, he wrote: "I'll always give my best to the fans and my teammates no matter what's going on".
"When we have everybody with you, everybody next to you know they want to fight for you, obviously it's going to be easier, you know?" he said.
Although some were surprised to see Pogba in action again so soon after his post-World Cup break, Mourinho insisted it was not a hard decision to play him because Pogba said he was ready.
It was very exciting to watch for the first 20 or 25 minutes but, when they took their foot off the gas, Leicester came right back into the game. For me, it was a dream come true.
They face Brighton away next Sunday and will be hoping that more of their players are back to peak fitness.
"Of course the performance wasn't the best, but it's better to start like this and finish well than start very well and finish bad".
