Sweden face Moldova in the Euro 2016 qualifier and Berg has been called up in the squad after his impressive displays with Panathinaikos this season.
The Swedish striker will probably sit on the bench, however, he is determined to fight for his place in the first eleven.
“I'll try hard in training to give Erik Hamren a headache. If we play the same formation as the last time with one striker and two wingers I won't have many chances. But you always have to fight, you never know. An injury may come up or a tactical change ahead of the game,” Berg quoted.
