James Pearce of the Liverpool Echo writes: “Reds doctor Andy Massey flew out to South America to conduct the necessary tests in Sao Paulo on Friday and Saturday.
“The 23-year-old attacking midfielder, who had already penned a five-year contract subject to the medical, was given a clean bill of health.”
The procedures were undertaken following Firmino’s participation in the Copa America in Chile.
The Brazil forward was central to the Selecao‘s progress to the quarter-finals, but he and fellow Liverpool man Philippe Coutinho were left deflated after being knocked out by Paraguay in a penalty shootout.
For the Reds, this is good news, with the pair set to join up with the squad midway through pre-season.
Pearce continues: “[Firmino and Coutinho] were given three weeks off after the tournament and they aren’t scheduled to link up with the Liverpool squad for another fortnight.
“That means they won’t be on the plane to Bangkok when Brendan Rodgers’ men embark on their pre-season tour of the Far East and Australia this Sunday.
“A decision has yet to be taken whether they will fly Down Under for the latter part of the tour which involves games against Thai All Stars (July 14), Brisbane Roar (July 17), Adelaide (July 20) and Malaysia XI (July 24).
“If Firmino does miss the entire tour, his eagerly-awaited debut is likely to be against HJK Helsinki in Finland on Saturday, August 1.”
