Seferovic's spot in Ottmar Hitzfeld's starting line-up could be under threat ahead of the FIFA World Cup with the Real Sociedad striker not having scored for Switzerland in almost a year, while Nuremburg's young attacker Josip Drmic is in impressive form.
With Switzerland far from prolific up front, Drmic's international scoring rate of three goals from six matches could tempt Hitzfeld to start the 21-year-old in Brazil.
On Saturday, Drmic came off the bench at half-time in Switzerland's friendly versus Jamaica, replacing Seferovic, and scored the winner in a 1-0 triumph.
Hitzfeld's side will play their second pre-tournament friendly in Luzern on Tuesday and the German coach will be hoping his team can put together a strong attacking performance ahead of their World Cup opener versus Ecuador on June 15.
Hitzfeld's other forward options in his 23-man squad are Zurich's Mario Gavranovic and Admir Mehmedi of Freiburg.
Gavranovic has scored four goals in eight games for Switzerland, Mehmedi has one in four, while Seferovic's record reads one in 10.
