Manchester City are certainly very happy to hear this news and hope that Mohammed Salah will be absent for quite a long time. They can more easily take advantage of Liverpool's current situation and at any time can displace Liverpool at the top of the standings. De Bruyne's return is an improvement in performance for Manchester City and the absence of Mohammed Salah will be a disaster for Liverpool.
Salah's predicted injury is a hamstring injury. I think it won't be too serious. In the short term, the Egyptian team will be directly affected if Salah is absent. As for Liverpool, their schedule this January is not too heavy, they only have to play one match in the Premier League against Bournemouth.
That's why Liverpool can completely give Salah the right to rest in the next few weeks if he is unfortunately injured. The Premier League championship race still has a long way to go. This is just a temporary shortfall for Liverpool. Mancity should not be too hasty to rejoice and lose focus.
But the problem is that there is no further confirmation on how long Salah will be absent from all competitions. Maybe it could be said that competing with Liverpool will be on time, but playing for Egypt at AFCON seems to have ended his hopes. Moreover, currently Egypt has only won 2 draws from 2 matches which makes them far behind from the main position in the group.
Things like this really drain his energy and thoughts because for Salah, both Egypt and Liverpool really need their role so that his team doesn't experience the slightest decline. It is certain that Salah will be fully rested and when he returns to Liverpool he will not be forced to play until his injury is completely healed and his body is fit again. Manchester City will take advantage of Salah's absence to continue their victory and Liverpool must be more alert in the next match because they are very vulnerable to losing points.
