Dominik Szoboszlai played when Liverpool beat Nottingham Forest, although only for a few minutes because he came on in the 76th minute to replace Harvey Elliot, so Dominik Szoboszlai will be fitter than Mohammad Salah in the match against Sparta Prague, and seeing Szoboszlai playing is much more likely than seeing Salah playing Later.
However, as you said, with the close match schedule against Manchester City which will be very decisive in maintaining their position at the top of the English Premier League standings, there is a greater chance that Mohammad Salah will not be deployed to make him fitter or if he is deployed, it will not be completely and will only look at the results of the match if necessary then he will play but if instead Liverpool are ahead then that is really unnecessary.
Jürgen Klopp's experience will allow him to correctly apply what should be applied in the match against Sparta Prague, especially since their opponent is not as strong as Liverpool even though they will field a lot of young players.
Atlanta being able to hold Sporting to a draw in the first match is a very good thing for them to win in the second match because the home position will give them an advantage. Even though they played as an away team, Atlanta managed to play well and provide resistance to Sporting, although there were doubts because they looked not in good shape due to two defeats in Serie A, and this result is their capital to get to the quarter-finals of the European League.
Tonight the game between Liverpool and Sparta Prague will played and it all seems like the big fish is going to outrun the host considering their heightened spirit all time in this season's UEL. Before the game week though, there have been speculations and fears about Salah not being on the line up list subsequent to his return to the team after a number of weeks out of play. They have what it takes to win the game today even though it's a much needed win for a confidence booster ahead of City's encounter over the weekend.
It's really impressive that even with the absence of Salah, past games in the league have been fruitful for them which gives them more push to bounce back and win tonight. For Sparta Praha, the game is very much important to them to gain a stance ahead of the advancement unto the next stage. They ought to be enthusiastic about the game and the eagerness to win should come alive more. It'd be more advantageous for them to maintain the lead as they'll be the host tonight and it'll be much needed to get them out of the danger zone of getting disqualified at this stage.
The team is top in their league table and so they have what it takes to compete well tonight. They are very competitive in their games and they really shouldn't be underrated as they're capable of anything that's fit to turn the game around. Weighing rightly, Liverpool currently have what it takes to earn the victory from the game tonight and maybe they'll do same when they meet City later. But I'm certain that it'll be tough inasmuch as the City side are doing better in performances too overtime.
