I hope Liverpool gets most of their players back before against the City, and stay fit until the end of the season.
They need their injured players back, but not just only for the City game; but to stay on the summit, because if they lose games against other opponents and beat City, it would not help their quest for the EPL title. Liverpool are missing quite a lot of their quality players right now through injury and they are in four competitions, if they don't get some of them back as soon as possible, it could have a negative impact on them, especially in the EPL.
We cannot be sure when the injured player will recover, it is difficult to predict depending on how the doctor says whether the player is fit or not, but if the player is injured longer then it will be troublesome for Liverpool, they will not do much except play makeshift players while quality players have to take a long rest.
What is feared is like last season when many quality players were injured it brought down Liverpool which became a slump because this could happen if many players were injured.
