One of the main issues surrounding Iran's Sardar Azmoun is whether we should be comparing him to Lionel Messi or Zlatan Ibrahimovic.
The forward is so highly-rated that fans back home are expecting him to become Persia's most successful footballer, and when Iran take to the pitch at this year's World Cup his name is likely to linger on the lips of spectators and commentators.
Azmoun is a forward who can head like Zlatan and run like Messi, but right now he is playing at Rubin Kazan rather than in one of Europe's big leagues—a fact that should change this summer.
