It looks like the Liverpool striker will be fit to face Spurs.
The Brazilian striker has been out of action since the 3-0 semi-final defeat by Barcelona 11 days ago.
Firmino won't be fit for Sunday's visit of Wolves as Klopp's side look to win the Premier League title.
But the Liverpool manager confirmed that he did expect him to make the showpiece against Tottenham in three weeks.
He told the Reds' official website: "Bobby not [available] for the weekend, but we have time [before the Champions League final] and that should be enough."
Having Firmino back would be a huge boost against Spurs.
Divock Origi, who scored twice as Liverpool did the impossible against Barcelona in midweek, has been a stunning deputy for the German boss.
But Firmino is on another level of importance, in terms of scoring goals and feeding Sadio Mane and Mo Salah.
Tottenham booked their spot in the final by coming from behind to beat Ajax on away goals on Wednesday.
