Newcastle United could send a huge statement to their Premier League rivals by securing the signature of Alexander Isak this summer. The Real Sociedad forward, 22, looks to have a bright future after impressing in La Liga over the last three years.
Isak honed his craft in Swedish as a youngster before Borussia Dortmund took a punt on him as a teenager. The German club quickly sold the attacker for a small profit as Sociedad managed to do a deal for around £9m.
His first season brought an impressive tally of 16 goals in all competitions but that total was dwarfed the very next year as Isak hit 17 league goals in 34 appearances. However, it was his exploits on the national stage that really caught the eye.
