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.
That wasn't looking serious because as the game got to the final stage of the game he got back up on his feet hoping they get to win the game but they failed.
Jurgen Klopp already wants him back because he knows how important Salah has been for the front line for Liverpool. He did not get the support he gets from liverpool yesterday though otherwise he wouldn't have been injured. He still among those having just a goal in the tournament. Martail remains with Man United and he will go nowhere.
