Newcastle United have less need to sell players this winter transfer window and Alexander Isak will likely stay at St James' Park until at least the end of this season.

Isak, 25, is still the subject of significant speculation regarding a move to Arsenal such is the north London club's need for a striker. The Sweden international, however, has previously said he does not want to leave Newcastle midway through the season.

Eddie Howe's side are also in an improved position than they were during the early stages of this summer concerning their Premier League profitability and sustainability compliance. That is especially after the recent verdict that no teams face a charge this season.

Speaking to the Chronicle, football finance expert at Sheffield Hallam University and Bet Ideas ambassador Dr Dan Plumley said: "Overall, there is a risk that good players move, and that is irrespective of all the other things we are going to mention. Fans will be wary of good players moving on and Newcastle are having a good season as well.

"That could mean that Newcastle feel they don't need to sell in this window. We know they are one of the clubs who were up against PSR and the manager himself has come out and said as much in the last few months.

"There was that movement of players last summer between Newcastle, Chelsea, Aston Villa and Everton where we saw players move around - some of whom were academy graduates, so that feeds into what we thought was happening with PSR. After the verdict a few days ago about no club being charged with PSR, that means there is a little pressure off.

"The bigger picture, looking ahead to the summer, is that we expect the Premier League to change their financial regulations. UEFA have moved to a new version of financial sustainability, which focuses on squad cost ratio.

"We know the Premier League are keen to move to something like that. This means the current regulations may not be in place next summer anyway.

"We know at the minute, there is less of a need for Newcastle to sell based on where they were a few months ago. I think he is likely to stay put in January, and then it will be a case of re-evaluating in the summer."
