Liverpool might have a hard time against them but I am least expecting them to let their hard down against sparta, they have a good defence that sparta might find a hard time breaking unless by counter measures, liverpool is back on form and salah has resumed from injuries, liverpool might be aiming to win the europa league since apart from the fa cup they are not in any big cup.
Sparta Praha team cannot be called weak at the moment. Sparta Praha lost 3-2 away match against Galatasaray. But Sparta Praha made a great comeback in the home match. The team won the home match by a huge margin of 4-1 and qualified for the round of 16. Sparta Praha's players proved their mettle. So it would be foolish to think that Liverpool can easily defeat Sparta Praha. The match will certainly be competitive. Sparta Praha players will do their best to win. Liverpool will have to perform well if they want to win. Liverpool have little chance of beating Sparta Praha, especially if the defenders don't play well.
The Liverpool team is under pressure at the moment. Firstly, several key players in their starting XI are injured. Especially the two main attacking players Salah and Nunez are not with the squad due to injuries. Also, Liverpool have a very busy schedule right now. Two days after the match against Sparta Praha, Liverpool will play against Manchester City. City must be beaten if they want to win the Premier League title. So I think Liverpool coach Klopp will not take the match against Sparta Praha seriously. Their main target is to perform well against Manchester City.
