Andy Madley went old school at the Amex - and might have cost Albion a winning goal.

The referee whistled straight away when he felt Leandro Trossard pushed Rayan Ait Nouri as they chased a long through ball from Robert Sanchez.

Replays suggested there was arguably no foul by Trossard, who went on fire the ball in the net.

Both the Belgian and Wolves keeper Rui Patricio were aware by then that the whistle had gone.

So Trossard would not necessarily have scored had he been allowed to continue.

Current practice is not to whistle - or raise the flag in the case of an assistant - straight away but allow a VAR check when the ball goes dead.

Michael Oliver gave an example of how that should work in a similar Albion comeback last season.

He penalised Glenn Murray for handball at West Ham but not until the ball had entered the net.

WHAT MAUPAY HAD TO SAY AT HALF-TIME

A VAR check confirmed Murray had not handled and the goal stood, securing a 3-3 draw.

Similar procedure should arguably have been followed this time.

Potter told The Argus after the match: “I said when I saw it live it was a bit soft but that’s probably my bias because you want it to go your way at that time. I haven't seen it back.”

But that was the point in a way. The men who make the decision didn’t see it back either even though they now have that opportunity.

ALBION PLAYER RATINGS

On review, they might have agreed it was a foul. Or maybe not.

But Madley took that option away.

Ian Wright told viewers of BBC’s Match Of The Day: “You look how far the referee is away from here and I’m thinking, with the equipment we have got now, let that go a little bit further, see how it goes, and then have a check.

"He says he has given it for a push, but I don't think he has pushed him there."

Trossard said: “I don't think it was a foul. He touched me, I think he fell over his own legs."
