Freddie Ljungberg has tipped Alexander Isak to take the next step and would welcome Arsenal signing his fellow Swede.
Isak, 25, has hugely impressed since arriving in the Premier League with Newcastle United two years ago. The striker fired them into the Champions League during an injury-affected debut season in England before becoming even more prolific last term.
Newcastle paid a club-record transfer fee when signing Isak but could already conceivably double the £63million deal they struck with Real Sociedad. Ljungberg hopes his compatriot will make another move to become an even better goalscorer.
