He is not expected to figure against Liverpool on Monday night.

Plenty have had their say on Isak's behaviour in order to engineer a move away, with Rooney admitting if he was a team-mate of the Swede, he wouldn't welcome him back.

While there is no evidence the Red Devils icon refused to train or play in the two instances he requested to leave Old Trafford, he stated there are correct ways to go about requesting an exit.

"If I'm a Newcastle player, I don't want Isak back," he said on the BBC's Wayne Rooney Show.

You can't go on strike, can't not turn up for training and train with your team-mates.

"If you want to leave the club or not, you have to be there for your team-mates and be ready if needed.

So I wouldn't want him back."

It was in 2010 when Rooney first submitted a transfer request to leave United but eventually opted to stay before signing a bumper five-year deal, as Ferguson ultimately turned a blind eye to the first saga where the player had wanted to join Chelsea.

It was only three years later, in Sir Alex Ferguson's last season in charge, that Rooney once again asked to leave the club, with the Scotsman confirming the club had refused his transfer request.

Ferguson admitted that was the reason Rooney was absent from his last home game in charge, which was a 2-1 win over Swansea.

He said: "I don't think Wayne was keen to play, simply because he has asked for a transfer."

Once again, Rooney was convinced to stay, this time under David Moyes, as he penned a contract extension with the club in February 2014.

Despite Rooney's claim that Isak can no longer make amends in the north east, he certainly was able to under both Ferguson and Moyes.

Rooney added: "Now, Newcastle aren't happy with Isak's behaviour because Liverpool want to sign him.

Once you've overstepped the mark I think it's very difficult to come back in.

"You can ask to leave a football club – that happens – or the club tell you you're leaving.

I think there are cases where it can happen, but from me as a person, don't think I could accept them back."

Newcastle will host Liverpool on Monday Night Football in their first home game of the season, which could prove to be an enthralling evening of action with plenty of emotions running high at St.
