Hackett, however, is firmly of the opinion that Timber should have been walking back to the dressing room early, in addition to the penalty call being missed. He maintains the evidence speaks for itself.

The former Professional Game Match Officials (PGMO) general manager told Football Insider: "Replays at half-time showed that Jurrien Timber escaped giving away a penalty kick. The video clearly shows him holding the shirt of Liverpool player Alexander Isak.

"VAR said everything was fine, but the Arsenal man had a fistful of the top. The referee should have been invited to view the monitor; this was a clear offence, and Liverpool should have had a penalty kick."

Hackett added: "Looking at that replay again, if the penalty kick had been awarded, then Timber should have been red carded for the denial of an obvious goal-scoring opportunity."

"He's going to head the ball in front of the goal, and they grab him where everyone sees the shirt. You don't need a lot, just to avoid Alex, because the ball just goes in front of him.

"I don't see why (it wasn't given); probably because he doesn't dive or go to the floor. It shouldn't be a reason not to concede a penalty."

"But then you're basically accepting that the first one is a pen, no? So you cannot use the argument in both ways differently. So I think it's a, yes, it's a pen; the Alex one is..

"It's not going to change anything if we talk to the PGMOL or not. I think we have to wait now; it's 10 or 12 days until they give the resolution. It's going to be what it is, and that's it; accept it and let's go for the next one, no? It's not going to change."
