Arsenal will need to come to a swift decision in the summer transfer window if they want to avoid losing another main transfer target.
According to The Mirror, Manchester United are reportedly keen on signing Alexander Isak this summer, with the Swede potentially replacing Cristiano Ronaldo. Chelsea are also thought to be interested.
The Gunners were heavily linked to the 22-year-old, who is valued at £36 million by Transfermarkt, towards the end of the January transfer window, but a deal never managed to materialise due to concerns over his £75 million release clause, The Athletic reported.
