Manchester United are hosting West Ham as they look to close the gap on the top four of the Premier League.
A poor run of results had seen Ole Gunnar Solskjaer’s side slip down to sixth in recent weeks.
And United took the lead in the 19th minute against Manuel Pellegrini’s side.
Referee Graham Scott pointed to the spot after Juan Mata was tackled by Robert Snodgrass following a ball in by Marcos Rojo.
Pogba slotted straight down the middle to give Manchester United the lead at Old Trafford but there was plenty of controversy over the awarding of the spot-kick.
And pictures show that Mata’s back foot was outside the box, while his standing leg was on the edge of the penalty area.
It was the 14th penalty awarded to Manchester United this season and came after Felipe Anderson had a goal ruled out for offside despite Diogo Dalot appearing to play him on.
And some football fans weren’t happy with the decisions by the officials.
One wrote: “The ref has given that penalty decision so quickly.. even without VAR why the rush? I make decisions every day at work.. I would never or never even claim to make them in half a second!”
Another simply added: “That was never a penalty”
A third wrote: “That was a never a penalty there but it has been given. Man United take the lead 1-0.”
And one other posted: “Never a penalty in a million years, next season with VAR West Ham would one nil up at the moment.”
With another agreeing: “Never a penalty lol and right after an onside goal ruled out.”
