Jürgen Klopp will assess whether changes are required for Liverpool's trip to Brighton & Hove Albion in the Emirates FA Cup.

The Reds have had over a week to prepare for the fourth-round tie at the Amex Stadium, as they look to deliver a much-improved performance following their last visit to the ground earlier this month. 

Fabio Carvalho and Nathaniel Phillips are doubts for the Reds in the 1.30pm GMT kick-off on Sunday due to minor fitness issues.

Asked about his selection plans, Klopp told reporters on Friday: “We didn't make these decisions yet. We have now a long training week – and after the game again – and that's something what we always use and everybody can show up. 

"If the boys who now started the games with the good spells look like they have to go again, then they will start again. 

"If not, thank God [we have options]. Up front not too many, Darwin is in – but in midfield we have a few options, I hope that stays like this and that's always good. 

"How I said, who is ready to defend is more than welcome in the team. The boys looked like they understood and now we have to show it on the pitch."

Luis Diaz, Roberto Firmino, Diogo Jota, Arthur Melo and Virgil van Dijk are all making good progress with their recovery from injury but still remain sidelined.

For Brighton, Adam Lallana won't play against his former club after sustaining a muscle injury in last Saturday’s 2-2 draw at Leicester City.

Centre-back Levi Colwill is also unavailable due to a quadriceps problem, while Jakub Moder remains out as he continues his rehabilitation from a cruciate ligament injury.

"Both Adam Lallana and Levi Colwill will miss the game," head coach Roberto De Zerbi said. “Lallana is one of the most important players in the squad, he will be out for a couple of weeks.

"We can play without Adam, or Alexis, for example, as we proved. We can do that because of the number of players, the young players are improving and are ready to play.

"It will be a different game, the last game was difficult, against Liverpool it will always be difficult. On Sunday we want to win and to play well. It's possible to play better than we did against Leicester."
