By the way, is Darwin Nunez's transfer information to Liverpool been confirmed?
If that happens, I don't think it's a threat to Sadio Mane, because Mane is playing pretty well with team-mate Mohamed Salah. On the other hand, it will threaten Diogo Jota and Roberto Firmino more, because if look at their contribution, Sadio Mane is still above the two players.
It has been confirmed and Nunez is now officially a Liverpool player and with a pretty fantastic contract and with a duration of 6 years.
The latest news is that at Liverpool he will wear the number 27 there.
For Mane he will no longer be at Liverpool, it seems, because seeing his press conference which said he wanted to seek new experiences and Bayern's incessant bidding, it was clear indications of him leaving would be very open this season.
