This summer, Isaac used the means of a strike to push himself to join Liverpool, while Visa also forced Brentford to sell himself to Newcastle in a similar way. Premier League legend Michael Irving expressed his opinion on this.

Irving said: "This may be the right thing to do, and those who firmly shout that morality may say that you need to lead by example at all times, but it depends on which side you are on.

"This is not new, it's actually happening all the time, and it's just that the transfer is too eye-catching. This may have happened 20 times in this summer window alone, but no one is as eye-catching as he Isaac, because it all happens in some small clubs.

"I felt this in every way during my career, absolutely. As long as the football industry exists, we will always see such things happening.

"I am not advocating Isaac's behavior, I want to say that we have to be objective and fair, because the clubs you sympathize with are likely to be the culprit of the incident. I just wanted to balance public opinion, not agree with his approach.

"If the same thing happened on the other side, you can't get angry at a player forcing himself to leave your home team. Visa did the same thing, what would Newcastle fans do? They were angry with Isaac, but I bet they would greet Visa with open arms.

"Liverpool is the same, Arnold left the team freely with the Boseman bill, which made the fans feel dissatisfied. But I'm sure that when the next player comes to shoot for free, they will definitely welcome him happily. This is football, I just can't stand this double-faced reaction. ”
