Manchester United's opening goal in Sunday's Premier League game against Liverpool was shrouded in controversy as Alexis Mac Allister was suffering with a head injury as Bryan Mbuemo tucked the ball into the back of the net. The ex-Brentford man netted within a minute of the game beginning at Anfield, as he slid the ball past Giorgi Mamardashvili with his right foot.

The goal came seconds after Virgil van Dijk challenged and won a header against Mbuemo near the center circle, and caught Mac Allister with his elbow in the process. Play should normally cease immediately when a head injury occurs, but referee Michael Oliver allowed the game to continue.

It's understood the official simply didn't see Mac Allister on the ground, hence his decision not to stop the game. The game was stopped for over three minutes as Mac Allister received treatment on the pitch.
