Football London reports that the Gunners are tracking Haaland and his team-mate Szoboszlai, who also been one of the key players in a 6-2 win over Genk.
The North London club approached Salzburg about securing the services of Szoboszlai during the summer transfer window.

The 18-year-old Hungarian has been on the radar of hosts of European teams including Serie A giants Inter Milan and Juventus.
Arsenal are hopeful their early contact with Salzburg will help position them as the frontrunners for Szoboszlai.
However, the North London club are not plotting a formal offer just yet for Szoboszlai or Haaland and will wait to see how their own young stars perform this campaign.
The Gunners representatives have been extensively scouting the Austrian Bundesliga after Sadio Mane and Naby keita were plucked from the league.
