You see, after that big victory over Manchester United, Liverpool didn't win a match, there were three defeats and only one draw with Chelsea. Those bad matches pushed Liverpool back to 8th place and they are now 10 points behind fourth place, which is a lot, and I'm not sure if it's possible for them to close that gap in 10 rounds left. Therefore, Arsenal will have more desire to win this match, but Liverpool are definitely capable of surprises.
Liverpool will not put all of their energy into this match after three defeats and one draw in a row, especially since they have lost hope of finishing in the top four in the Premier League. Football is full of surprises, but sometimes you can be certain that no surprises are on the way from a team based on how they're currently playing. Arsenal is competing for the league title, so I believe they will be fully prepared to win this match without a doubt.
