The Dinamo Zagreb striker was the star of the show in last Thursday's 7-0 win against Liechtenstein and is expected to get the nod alongside Haris Seferovic in Baku.
Xherdan Shaqiri should start just off the two strikers, while Granit Xhaka is favourite to get the nod in the deeper midfield position.
It is then a choice between Denis Zakaria and Remo Freuler for the other spot alongside Xhaka, with Ricardo Rodriguez and Kevin Mbabu the most likely to start out wide.
That is assuming that Vladimir Petkovic uses his usual 3-4-1-2 formation, which would see Nico Elvedi, Manuel Akanji and Fabian Schar operate across the back.
However, Petkovic also has the option of tucking versatile Torino ace Rodriguez inside as part of the back three.
Switzerland possible starting lineup: Sommer; Elvedi, Akanji, Schar; Mbabu, Xhaka, Freuler, Rodriguez; Shaqiri; Gavranovic, Seferovic
