Former Premier League striker Chris Sutton says the rule is well known among the players.
“It’s smart by Luis Diaz because he knows he’s with him when Tarkovsky hit him,” he told the BBC Sport.
“I don’t think changing the rules is a good idea. It is more complicated than this one scenario, because without this objective element, you go back to where everything is offside.
“If you are Everton, you will feel a little weight – I get that. But not everything can be black and white unless you want to go back to the days when someone is offside, it was the call.
Liverpool left defender Stephen Warnook had a different view on the BBC Radio 5 Life.
“This is a problem in the book of Laws and is where it comes from,” he said.
“Because they look at the list of things and go: ‘Did that interference in playing? No.
“Well, in fact, he’s actually if you’ve played and understand the game.
“If you have a couple of help behind me and I will defend the edge of the box, my body is always on the half-rotation.
“Do you come and you’re not in front of me? You are doing a move and trying to reach yourself with you? So I always have a reaction to you.
“And if you go inside and talk to all the previous professional players in the training centers or wherever they are, ‘Do he be active in this position?’ They all said, ‘He has an impact on me, 100%’.
“But there’s a list of Tik-Boxes in offside rules, and that’s an issue.
