West Ham Fan's Attempt To 'Prove' Edinson Cavani Was Offside Is So Laughable, It's Gone Viral

A West Ham fan's attempt to prove Edinson Cavani was offside in the build-up to Manchester United's winner has gone viral, for all the wrong reasons.

Marcus Rashford dramatically earned United a 1-0 win in the 93rd minute to send Old Trafford into a frenzy on Saturday afternoon.

Controversy followed as many believed Cavani, who provided the assist, was offside. VAR checked the goal and Aaron Cresswell was playing the Uruguayan on from left-back.

Hammersline on Twitter still doesn't believe Cavani was onside however.

"The only way to get accurate lines is from the actual outline of the box so all you do is drag it along and you can clearly see how off Cavani is," he said before drawing lines on Snapchat.

He attempted to use the edge of the box as the lines to prove Cavani was offside and if you use that method, he is offside.

VAR is more than Snapchat though. Who knew?

Fans on social media saw the funny side and reacted exactly the way you think they would.

One said: "Surely grown adults don’t think this is how angles work?"

Another commented: "Stay in school kids, just stay in school."

A third put: "Thats some world class geometry right there."

While someone stated: "Oh my I'm in tears, we've rattled everyone by scoring a goal."

Victory over the Hammers means United have won back-to-back games under interim manager Ralf Rangnick for the first time.

The Red Devils have replaced West Ham in the top four going into the international break and Rangnick was delighted with his side's performance.

He told Sky Sports: “If I look at the shots on goal and the chances during the game, I think we deserved a 1-0 win.

“For me, it was clear from the very beginning it would take some patience against a well-organised team like West Ham.

"It was not always easy for us to find the best possible solutions in the final third.

"Defensively I think it was probably the best performance in the last eight weeks, the way that we were always trying to win balls back, our counter-pressing.

"The physicality of the game was really outstanding and we know we still have to improve with possession of the ball."

Rangnick has granted his players time off over the break and they return to action on February 4 against Middlesbrough in the FA Cup.
