Ostersunds striker Saman Ghoddos is on the radar of West Ham and Leicester City.
Arsenal narrowly beat the Swedish giants in the last 32 tie, but the Iranian striker stole the show and is now a top target for several clubs, according to ESPN.
After the first leg at the Jamtkraft Arena, Gunners boss Arsene Wenger was quick to praise his performance.
He said: "Technically and tactically, I was impressed by him."
The Swedish-born star then set up two goals in the second leg as Ostersunds thumped Arsenal 2-1.
