Chelsea and Manchester United lock horns at Stamford Bridge this afternoon in the latest clash between the two titans of English football.
Both sides have been in sensational form recently, with Thomas Tuchel yet to taste defeat as Blues boss and United losing just twice in the league since the start of November.
The two teams are both competing to secure a top-four finish and the prize of Champions League football this season, a fight which has become extremely tight due to the excellent form of Leicester City, Everton and West Ham.
Picking up points against a direct rival, therefore, could be extremely decisive and United seemed to have a golden opportunity in the first half.
Following a Marcus Rashford free-kick that was parried away by Chelsea keeper Edouard Mendy, Callum Hudson-Odoi appeared to strike the ball with his arm on two occasions.
United forward Mason Greenwood also seemed to hit the ball with his arm but his touch occurred after the first from his England teammate.
It appeared that the referee would point to the spot but, following a VAR decision and a view on the pitch side monitor, it was decided that there was no infringement.
That left United fans on social media furious as they believed it was a blatant penalty, taking the opportunity to hit out at rival fans who suggest they often benefit from VAR decisions.
Plenty had their say on the incident, which left supporters scratching their heads as, though the decision would have been harsh, there has been a number of similar incidents so far this season.
The decision is likely to be heavily analysed after the match, particularly if United do not go on to take all three points.
