Mane and Firmino combined with Salah very well and they were beneficial with each other. Together, they played better in Liverpool and we saw each of them played worse if they did not have other two players to play together.
Mane and Firmino have both left Liverpool and it will be difficult for Liverpool to replace their former two players as Mohamed Salah has previously been able to do well with their combination up front.
Now Liverpool must really look for two substitute players who can coordinate well with Salah so they can have a good front line.
But I heard that Liverpool are eyeing Ricardo Pepi to collaborate with Mohamed Salah.
