Los Blancos join Arsenal in the quest to snatch the 21-year-old, whom they see as an alternative to Mbappe or Haaland.
But the Gunners are considering paying Real Sociedad's £60m release clause to avoid entering negotiations. Arsenal are also eyeing Everton's Dominic Calvert-Lewin as Lacazette's replacement, the latter of whom would have to be sold first.
Isak's 8 successful dribbles rank him top amongst players in the tournament. Frankie De Jong has 13.
The 6-foot-3 agile striker scored 17 goals and provided 2 assists in 34 La Liga appearances last season.
