Klopp's Melwood injury update: Lallana, Wijnaldum and Lovren latest
Jürgen Klopp has confirmed Dejan Lovren and Nathaniel Clyne are 'in the race' for a starting berth against Manchester United on Monday evening after overcoming their respective injuries.
And the Reds boss has refused to rule either Georginio Wijnaldum or Adam Lallana out of the Anfield meeting with Jose Mourinho's men, with the pair set to be given time to prove their fitness in the coming days.
Lallana was forced off with a groin problem during the 2-1 win over Swansea City that preceded the international break, while Clyne (knee) and Lovren (groin) were also unable to represent their countries after sustaining injuries in that fixture.
Wijnaldum, meanwhile, had to be withdrawn 62 minutes into the Netherlands' 1-0 defeat to France on October 10 after picking up what appeared to be a hamstring issue.
But all four players could yet feature against the Red Devils next week, Klopp has now revealed, with his two defensive concerns most likely to return.
"[They are] not too bad but it's a question of perspective, I would say," the German told reporters.
"In this moment, we don’t know exactly who is available. We all know about the obvious issues with Gini and Adam but they are both not ruled out for Monday.
"Four session to go sounds long, but [it's] only four sessions to go, so we have to see. I don't have to make a decision now, so I can wait until I make my final decision and we will have a really good team on the pitch I'm sure.
"Dejan and Nathaniel trained Tuesday and Wednesday so they are in the race."

Brazil duo Roberto Firmino and Philippe Coutinho returned to Melwood later than their fellow internationals having travelled as far as Venezuela for a World Cup qualifying fixture.
But the extra days of rest provided by a Monday kick-off will be helpful to their recovery, Klopp believes.
"It’s a big impact. It means we have four sessions to go until Monday night and that means that a lot of things can happen," he added. "I've made no decision yet.
"They came back, they did what they had to do until now. Roberto [did] a little bit more in the last session, Phil played nearly two complete games so he had only recovery after a long, long flight.
"Even after the club did everything to bring them as comfortably as possible back to England, it's still a long trip.
"So, it's still in their legs but each day, each hour helps until the next game and so that we play on Monday is an advantage in this case, of course."
