And there were plenty of jokes and memes flying about on social media soon after the ball hit the back of the net.
That's the verdict of Sky Sports pundit Phil Thompson following the club's disastrous deadline day.
Not many players have the confidence to do produce such a run up but it was always to be expected from Pogba, who did something similar at the age of 17 against Liverpool. (It was) weird. I was thinking, "You've got to score".
Pogba scored the first league goal of the season from the spot after only three minutes following an inexplicable handball by Daniel Amartey inside the Foxes' box.
"We don't really have one [penalty taker]", Pogba said after the match. "Even if the manager puts down the names, it's about how we feel. I am happy with the performance to make this game in this condition, it's encouraging for the future".

'Of course, we have second or third choice in case he is not confident or for some reason doesn't want to take it.
The Red Devils haven't won the Premier League title since Sir Alex Ferguson's retirement in 2013.
"Jose Mourinho is a great manager, one of the best managers in the world over the last 15 years and will go down in history". "It's a good way to start the Premier League".
Nonetheless Mourinho was pleased with his team's display, singling out Pogba and Shaw for particular praise, and the overall spirit. "We thought maximum [he would play] 60 minutes, but he managed more than 80".
'Paul was fantastic. His contribution was awesome. We were in trouble. I need more changes. "I think we are more the head coach than the manager", he said. "All my players did not have 90 minutes in their legs and bodies".
Matteo Darmian tested Leicester goalkeeper Kasper Schmeichel at the near post early into a second half that United started with bundles of possession, but few clear-cut chances. "The decision belonged to him, because Andreas Pereira comes from Valencia bench as a winger to play number six; Fred had 10 days training, Ukrainian league, comes direct to Old Trafford; Ander Herrera injured".
"It will be a hard season for everybody, not just for us", the 55-year-old said.
