Sadio Mane came up with a new way to catch Romelu Lukaku offside

Liverpool FC v Manchester United - Premier League

What a week for Liverpool Football Club.

On Tuesday, Jurgen Klopp’s side knew they needed to beat Napoli to stand any chance of qualifying for the last-16 of the Champions League.

They did just that with a nervy 1-0 victory.

Then, five days later, they welcomed arch-rivals Manchester United to Anfield.

But it almost a nightmare start for the home side.

After just four minutes, Ashley Young whipped in a free-kick which evaded everyone and landed inside the far post.

However, Romelu Lukaku was clearly stood in an offside position and attempted to play the ball and, therefore, interfering with the play.

The assistant referee raised his flag and the goal was rightly chalked off.

However, replays showed exactly why Lukaku was stood in a clear offside position.

Before Young swung in the free-kick, Sadio Mane gave Lukaku a big push into an offside position.

Twenty minutes later, Mane was involved once again.
