AC Milan are threatening Arsenal's plans for Real Sociedad striker Alexander Isak today.

Mundo Deportivo says Arsenal were initially confident they could negotiate a fee lower than the Swede's release clause but they have now been told by Sociedad they will need to pay the full amount, which is £75.4million, if the striker is to leave this month.

The Gunners seem to be on the fence on whether they should give into Sociedad's demands or go back in for Isak in the summer when his price would potentially be reduced.

But reports that AC Milan are also considering a move for the 22-year-old might force Arsenal's hand.

It's claimed the Italians view Isak as a potential long-term replacement for Zlatan Ibrahimovich.

Isak added fuel to the fire he was Arsenal bound when he was spotted in London over the weekend.
