Buoyed by their progress to the last 16 of the Europa League, where they will take on rivals Manchester United, Liverpool now turn towards Sunday’s trip to Wembley Stadium.
With the majority of the players to take part in Thursday night’s 1-0 win training indoors, Klopp led a intensive session with the rest of his squad.
The quartet could return to Klopp’s squad against City, with the German telling reporters on Friday how selecting his side would be “the most difficult thing I’ve had to do until now.”
“We had a few problems since I’m here, but we’ve never had the problem where we’ve had too many players,” he said.
“It’s the most difficult thing I’ve had to do until now.
“A few players will be disappointed.
“This morning I had 30 players in training, and it was the highest level.
“I don’t want to say this was because it’s the final, but it was the highest level!
“Now I have to make decisions. I will make them, it’s no problem.”
Joining Lallana, Allen, Skrtel and Lovren in Klopp’s plans could be Jon Flanagan and Jordon Ibe, with the former missing out on Thursday after being omitted from Liverpool’s Europa League squad.
Ibe’s absence from the squad against Augsburg was likely a tactical decision, but the winger could return against City.
