Jurgen Klopp spoke to reporters at Melwood ahead of Liverpool's Premier League clash against Brighton on Saturday.
The Reds welcome Graham Potter's side to Anfield on as they look to further consolidate their position at the top of the Premier League table.
With Liverpool having played an intense 90 minutes against Napoli in midweek, Klopp insisted his side must be ready against an "exciting" Brighton side.
“We play Brighton with a very, very exciting development,” Klopp told reporters.
“When you see them playing now – how they play, the way they play, the possession they have; I think they are seventh or so for possession in the league. Against City they had 48 [per cent] or so, they play proper football.
“They really have their own plan and I respect that a lot. Graham is doing a really good job there. It’s just a tough one.
“After that game pretty much everybody has three games a week coming up now with different cup competitions. But Brighton had a full week to prepare and they are innovative.
“They think a lot about football obviously, and so they will come here and try to get the points. I’m 100 per cent sure, no doubt about that. And we have to be ready, three days after a very intense game against Napoli.”
“Of course, that's absolutely bad news. Nothing good to say about that,” Klopp said on Fabinho's absence. “About a timeframe or how long it will take, we are not sure.
“But it looks pretty sure that he will not be involved in the Christmas fixtures, let me say it like this. It obviously takes a while.”
Fabinho would have been absent from this weekend's fixture due to suspension, however, his prolonged absence will be a big blow to the way the Reds usually set up.
It will be intriguing to see whether his replacement - whether that be Adam Lallana, Alex Oxlade-Chamberlain, James Milner or Naby Keita - is able to come into the side against the Seagulls and make an instant impact.
