Roberto Firminho will make his return from a hamstring injury.
The German coach has confirmed that a host of first-team players will be available for the weekend’s Premier League clash against Brentford.
Klopp said: “Trent was not injured, Trent was a little bit ill. He’s back in training, trained yesterday and will be fine.
“Neco made [his] first steps the day before yesterday; yesterday a [recovery] day; will be in training today, if it’s 100 per cent, we will see how he can cope with it.
“James was a similar thing to Trent, so he should be recovered. I saw him running around here, nobody told me differently – I assume he will be in training today.
“Naby probably not. It’s not a serious thing but we have to wait until the pain settles, pretty much. We will see about that. Thiago, no chance.
“Bobby trained already for two or three days, so he is back in contention, let me say it like this. We used him a little bit as a ‘joker’ [in training].
“But he will be in the normal training and then we have to make a decision if we take him with us or not. Porto, 100 per cent. Brentford, we have to see.”
