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.
The news about the gravity of the hamstring injury might be out today after a proper medical checkup. Both Egypt and Liverpool will be hoping that that injury is not that serious. His absence will have some negative impact on the Pharaohs as we saw the Ghanaian fans cheering when they saw that he was injured. Everyone knows that Salah is a threat to any defense. Liverpool will want him back as soon as possible to get the best medical treatment because they need the striker to fight for all the competitions they intend to win this season.
Liverpool is the team most worried about this news because Salah is one of their mainstay players which of course will have quite an impact on the Liverpool team's performance if Salah is absent due to injury.
The injury suffered by Salah has not been confirmed whether it is dangerous, it will take a long time or not, but what is clear is that the Egyptian team is also quite disadvantaged by this, especially in this match, Egypt drew 2-2 in Group B of the African Cup of Nations and this is the second time they have achieved a draw.
Mohammed Salah's injury isn't expected to last longer than one more week according to reports as he's very likely to play in his country's last group game in the African Cup Of Nations. Liverpool this weekend will play their against will play against Bournemouth in the English Premier League and will need a win in that game to further cement their place at the top of the league table and they'll be doing that without Mohammed Salah.
Many people are of the opinion that since Salah won't feature for Liverpool in that game, they're very likely to lose it and that I think is a big lie because Liverpool is full of top quality footballers who can easily win games for the club in Salah's absence. That game will be played at Anfield and expect nothing but a Liverpool win.
