Firmino and Thiago have been sidelined through injury, while Matip sat out the weekend's victory over West Ham United due to illness. The trio will now be assessed ahead of Liverpool's Champions League last-16 second leg with Internazionale at Anfield on Tuesday evening.Klopp told a press conference: "I think all trained yesterday fully. I'm not sure yet what we make of that exactly, to be honest, because we have to see how they react. "So, Thiago was only a week out, probably will be fine but we have to wait for it. Joel was only three or four days I think, so he is fine, I would say. "With Bobby, it was longer out, it was [his] first session, so we have to see if we have to stress that or if it makes probably sense to give him just a few more days with proper training. "Because we obviously don't train properly today, it's a minus-one session, it's tactical stuff, not high intensity and Bobby might need something else. We will see that."But they are all in training."
