Liverpool defender Trent Alexander-Arnold and forward Diogo Jota are expected to be available for Saturday's Premier League game at Watford.
Alexander-Arnold missed Liverpool's Champions League win over Porto and the Premier League draw with Manchester City due to a muscle issue, while Jota sat out Portugal's matches last week due to an injury.
Midfielder Thiago Alcantara is recovering from a calf injury and Klopp said the Spain international will likely miss the trip to Vicarage Road.
"So it looks really like Trent and Diogo will be fine, they will train with us tomorrow (Thursday) completely normal, that's the plan," Liverpool manager Juergen Klopp told the club's Liverpool's website on Wednesday.
"Thiago needs probably a little bit longer, (he) was not in team training yet - that's always not a good sign for starting the next game."
Liverpool are second on 15 points, one behind Chelsea.
This will be the first Premier League match between the teams since February 2020, when Watford beat Liverpool 3-0 to end their club-record 44-match unbeaten league run.
Watford for the first time will have Claudio Ranieri in charge. The Italian has won four of his five Premier League home matches against Liverpool and shocked the football world by winning the Premier League with Leicester City.
Leaders Chelsea travel to new boys Brentford, who became the first team in the Premier League to remain unbeaten in their first three London derbies after wins over Arsenal and West Ham United and a draw with Crystal Palace.
Chelsea have won each of their last six away London derbies in the Premier League and boast more different goalscorers - 12 excluding own goals - than any other Premier League side this season.
Manchester City, meanwhile, are looking to become the first team in English soccer to win five straight home matches against one club one club by five or more goals.
Burnley have lost each of their last eight games against City in all competitions.
City's Riyad Mahrez has scored eight Premier League goals against Burnley, more than he has against any other side in the league.
After beating Manchester United 2-1 at Old Trafford in May, Brendan Rodger's Leicester City host the Red Devils at the King Power Stadium.
United are aiming to stretch their unbeaten away run in the league to 30 matches after 19 wins and 10 draws, with Ole Gunnar Solskjaer's men looking to come away with maximum points after drawing with Everton at home.
But it won't be easy as Leicester striker Jamie Vardy has scored in each of his last three Premier League games, plus United are struggling at the back with serious injury concerns to central defenders Raphael Varane (thigh) and skipper Harry Maguire (calf).
