Jurgen Klopp has hinted Liverpool could change formation for Sunday's clash with Man City at Anfield.
The Reds are without Trent Alexander-Arnold through injury for the game, with James Milner the man chosen to deputise for recent victories over Crystal Palace and Porto.
With whoever Liverpool choose to replace the England international likely to line up against Joao Cancelo and Jack Grealish, Klopp insisted the Reds have enough options to cover Alexander-Arnold's absence for the match.
However, he didn't confirm if Milner would retain his place when hinting he could even consider a formation change against the Premier League champions.

"We do a line up and it's not clear," Klopp told reporters. "We have three, maybe more, options for the position and we will see which one we choose.
"We have James, we have Joe, we have Neco. We could change system, there are quite a few things. We have time to train this week so there are a lot of things possible but football is not a game anymore where you should have these one-one challenges for a long time.
"There are moments but whoever plays there should be protected by at least two players. That's the right centre-half and a central midfielder, and the winger is also around.
"Whoever plays there should not be afraid of being alone against really good football players for a long time, but I don't know who will play for City in this moment.
"It doesn't make sense to think too much about it. We have to defend as a unit and if we do that, it's tricky for everybody but there will be moments where individual quality will shine for both sides and hopefully in the end it'll be good enough for us."
