Roberto Firmino has not been included in Brazil's official 18-man squad for the 2016 Olympic Games, leaving the forward free to enjoy a full pre-season with Liverpool.

He was left out of their provisional squad, named earlier this month, but the official confirmation of his absence from coach Rogerio Micale's squad was delivered on Wednesday when their final selection was made public.

They were allowed three over-23 players for their squad, with Firmino thought to be in contention, but Micale has opted to pick goalkeeper Fernando Prass and forwards Douglas Costa and Neymar of Bayern Munich and Barcelona.

It will be a blow for Firmino, who also missed out on their squad for the Copa America Centenario in United States this summer. There, Dunga's side - including Liverpool teammate Philippe Coutinho - crashed out in the group stages after only beating Haiti.

The Olympics is the only major football tournament that Brazil are yet to win as a nation and their desperation to win it in Rio de Janiero this summer saw them spare Neymar for it, as opposed to using him in the Copa America. 

Of the other notable inclusions in the squad, Paris Saint-Germain centre-back Marquinhos joins Barcelona's Rafinha, Lazio's Felipe Anderson and highly-rated young attacker Gabriel Barbosa of Santos with the Brazilians bidding for a maiden gold medal in men's football. 

Firmino set for full pre-season with Klopp and co.

But Firmino will not join his compatriots and rather, will get the opportunity to take part in all of the Reds' friendlies, starting with four domestic fixtures in early July.

He will then be part of the Liverpool contingent for their tour of the United States, where Coutinho will join up with him, before clashes with Barcelona and Mainz the penultimate weekend before the start of the 2016-17 season.

Coutinho, the only Reds representative at the Copa America, could also return for their return to the US while summer signing Loris Karius is not expected to be named as part of Germany's squad for the Rio Olympics, the goalkeeper instead to take part in a full pre-season with the Reds.

Firmino scored 11 goals in 49 appearances across all competitions, adding nine assists, in his maiden season on Merseyside last term and will undoubtedly be an integral part of Jürgen Klopp's attack moving forward.

The former Hoffenheim player, who joined in a £29 million last summer, would have likely missed the opening Premier League fixtures against Arsenal and Burnley on August 13 and August 20 were he selected.
