Brazil's joint-record goalscorer may have seen his future in the national side in jeopardy after leaving European football for the Gulf State, but it appears he remains in the plans of the setup.
Diniz has an even more difficult decision in attack though, of whether to choose Gabriel Jesus or Richarlison in a central role.
Jesus capped off a good performance with an excellent goal against Manchester United at the weekend, putting the icing on the cake with the final goal in a 3-1 win.
Richarlison meanwhile, has endured a difficult time trying to fill Harry Kane's boots at Tottenham Hotspur, and he was dropped for their 5-2 win over Burnley at the weekend, and could also lose his place for the Selecao.
Jesus and Richarlison are among a 10-man Premier League contingent in the Brazil squad, with Alisson and Ederson set to compete for a place in goal again, while Newcastle United duo Joelinton and Bruno Guimaraes could both feature.
Arsenal's Gabriel Magalhaes has received his first call up and could make his debut here with Eder Militao being left out of the squad.
Militao's Real Madrid teammate Vinicius Junior is the most notable injury absentee for the upcoming break, while Lucas Paqueta has also been dropped.
There are three other uncapped players in the squad, one of whom is Caio Henrique, and the left-back could make his international debut, with Monaco teammate Vanderson on the opposite flank.
The other uncapped players are Nino and Lucas Perri, just two of the four home-based players in the squad, along with Andre and Raphael Veiga, who could both get minutes in midfield in what should be the most straightforward fixture in the qualifying campaign.
Brazil possible starting lineup:
Alisson; Vanderson, Marquinhos, Gabriel, Caio Henrique; Casemiro, Bruno Guimaraes, Joelinton; Raphinha, Gabriel Jesus, Neymar
