The No.9 is now back in full training, having been sidelined with the muscle issue he sustained away at Internazionale in the Champions League last month. Speaking about Firmino at his pre-match press conference on Friday morning, Klopp said: "Yes, he is back."Asked for a squad fitness update, the Reds boss continued: "We had a few little things but so far nobody is out of training. "We have on top of that, how everywhere, COVID is not over, so these kind of things we have as well – or had. We will see how that's going on. "We try absolutely everything to avoid this but it's obviously not really possible. Players or staff who had it now have absolutely no symptoms, that's good but they cannot be involved. We will see. "They come later today, so we train a bit later, they're not here yet. And so far I didn't get any news. "Injury-wise, I think they all should be ready."
