Recently, in an interview, Cascarino talked about Isaac's departure from the team for training, and he believed that such a way of handling it was not advisable.

Cascarino said: "This is very common among players. I always say that if you sign a contract, you have to comply. Even if other clubs throw you olive branches, you have signed it."

"His contract with Newcastle has expired for three years, which puts him in a very embarrassing position. I don't agree with the behavior of some players. Isaac is training at Real Sociedad, and he might do it if he was injured before, but I think there should be a bottom line."

"You have to be careful with the club you are in, and his pre-season preparation is distracted. It's not Liverpool or Newcastle's fault. Sometimes the responsibility lies with the player himself, he needs to deal with the problem in the right way, and he doesn't need to take extreme measures like he did. "

" Sometimes, someone might suggest you to raise some disputes, upset some people, show your position, in order to facilitate the transfer. But Newcastle is a big club, and I understand you may think there will be more opportunities in Liverpool because Liverpool is very ambitious in the transfer market and won the championship last year. I understand all this, but you can't get angry every time things are not going well."
