Manchester United are reportedly keen on signing top Arsenal attacking target Alexander Isak this summer, with the Swede potentially replacing Mason Greenwood.

The Red Devils are ready to back whoever takes over from Ralf Rangnick as permanent Old Trafford boss at the end of the season. And according to a report in the Daily Mirror, the Real Sociedad forward is now firmly on their radar.

The 22-year-old has been strongly tipped to join the Gunners this summer after being spotted in London last week. Indeed, Isak has been tipped to move to north London as part of a £180million triple deal.

But given United’s financial prowess, they might be able to swoop in and sign the talented Swede.

However, Isak will not come cheap as he currently has a whopping £75million buyout clause.

But it’s Arsenal who remain favourites to land Isak, with Rio Ferdinand backing the proposed switch.

The former United defender said last month: “He will be a good signing.

“Another young talented player. He has done really well in the Euros for Sweden, I thought.

“He is a talented player, man.”

Isak, who has won 32 caps for Sweden, has scored 71 career goals in 175 appearances.
