Arsenal seemingly could sign Alexander Isak during the winter transfer window while complying with Premier League profitability and sustainability rules.

The Gunners spent around £100 million during the summer, signing David Raya, Mikel Merino and Riccardo Calafiori. However, they also recouped roughly £90 million from selling Aaron Ramsdale, Eddie Nketiah and Emile Smith Rowe.

Those moves mean the club has the funds to spend this month, with additions in forward areas being their most pressing priority. That is especially the case after failing to score for the sixth time this season against Newcastle United in their semi-final first leg.

That team standing between Arsenal and a first League Cup final for seven years was also responsible for the third. Alexander Isak scored the only goal when they met at St James' Park in early November.

The striker had no goals against the Gunners in his first two games against them but now has two in as many matches after opening the scoring at the Emirates Stadium. That strike was Isak's 50th for Newcastle, with only Erling Haaland and Mohamed Salah scoring more since his move to the Premier League two-and-a-half years ago.

Understandably, Newcastle reportedly value the player at over £150 million. That is around triple the release fee Manchester City paid Borussia Dortmund for Haaland and the same amount Liverpool rejected 18 months ago from Saudi Pro League side Al Ittihad for Salah.

The Gunners, on paper, could conceivably offer Newcastle around that fee for Isak. As explained by Kieron O'Connor, the man behind the Swiss Ramble blog, there is an assumption that the club could post a £164m loss this season if their level of allowable deductions stays the same. football.london understands, though, that their lack of offensive signings is unlikely to change this transfer window.
