The Brazilian had only played the final five minutes of the Reds’ FA Cup semi-final win on Saturday but it was then that he picked up his injury.
“Bobby was not involved because in the very last situation of the City game he got something on his foot,” Klopp told Sky Sports. “It’s not really bad.”
“We hope so [that he can be involved vs. Everton].
“Actually, we were a bit worried but the scan was fine. But it’s still very painful and that’s why there was no chance [against Man United].”
That Liverpool has a near five-day break between United’s visit and Everton‘s bodes well for Firmino to prove his fitness and offer Klopp an option to rotate through his formidable forward line.
With Mane, Salah, Jota and Diaz all in form, adding Firmino back into the mix makes for a scary proposition for the opposition and an exciting one for Reds with nine, possibly 10, games remaining.
