If Mohamed Salah's injury is serious, it wouldn't be good for Liverpool. Losing their best players in a mid-season African Cup will end their leadership joy. Hamstring injuries can be serious.
The moment Liverpool make a mistake, Manchester City take the lead and never let it go. From then on, the balance in the Premier League will not change easily. City had given other teams enough advances. Liverpool and Arsenal couldn't use this well. They needed to collect more points. City with De Bruyne won't lose points easily anymore.
I hope M. Salah does not suffer a serious injury and based on the 3sport report, it is said that M. Salah was seen walking normally when crossing the mixed zone after the match.
1With this, it looks like Liverpool's worries will be somewhat alleviated. But still the situation is not clear at this time. Maybe we have to wait for the latest news from the further medical examination that is being carried out on M. Salah. But if M. Salah turns out to have a hamstring injury and it is quite serious then Liverpool will indeed suffer the biggest loss. Because Liverpool will definitely have difficulty maintaining the top of the standings without their mainstay striker.
