A late Arsenal move for Alexander Isak isn’t being ruled out, with technical director Edu Gaspar working hard on a deal.

Football.London report that Arsenal are continuing to push for the signing of Alexander Isak.
The deal is complicated by the player’s high release clause, but Edu is working hard on a move, so a late transfer cannot be ruled out.
Mundo Deportivo covered claims on Sunday that Arsenal had made a €70m (£58m) bid for Isak last week, but that wouldn’t be enough to complete a deal. Real Sociedad want the player’s full €90m (£75m) release clause.
The Telegraph confirm that Sociedad president Jokin Aperribay is determined for Isak to stay and won’t negotiate his departure. Isak himself is back in Spain after a brief holiday visit to London.
As a result, the deal would only be a realistic possibility if Arsenal plan to buy the release clause. A club-record fee, with only hours to pay it and to complete all the other intricacies of a transfer. It seems unlikely.

Real Sociedad nerves can be assuaged by the fact that La Liga gives an extra month to sign a replacement (from La Liga) to any club that lose a player via release-clause activation on deadline day.
So the Spanish club know that as long as they hold out for the release clause, they’ll have €90m and a month to sign an alternative from within their league.
Yet another reason for them not to negotiate a lower fee.
