MatchLiverpool v Villarreal: Champions League team news
Roberto Firmino looks set to miss out on Wednesday night's Anfield encounter, however, but is edging closer to a return to full training.
The No.9 has missed the Reds' last two matches with the foot injury he sustained at Wembley against Manchester City in the Emirates FA Cup.
"I don't think [he is ready] yet," Klopp told Liverpoolfc.com on Tuesday. "He is running outside and that's good, obviously, but I am not sure.
"Maybe somebody will surprise me afterwards and tell me, 'Yes, Bobby is in.' [I will have] open arms, but I don't think so.
"Apart from that, no [new injuries] that I know yet."
For Villarreal, Yeremy Pino has been ruled out due to injury, while the fitness of forward Gerard Moreno will be closely monitored as he recovers from a hamstring issue.
Former Liverpool left-back Alberto Moreno is unavailable after tearing his anterior cruciate ligament in early March.
"Yeremy Pino is going to be missing, he has an injury that is dragging on," boss Unai Emery said at his pre-match press conference. "He trained yesterday but he won't be able to play.
"Gerard Moreno is working well, and the idea is that he will pick up the pace tomorrow. Francis Coquelin has trained as normal."
