Koulibaly is being linked with a €90m move to Liverpool.
The Daily Express says the two Senegal internationals are the pride of Aliou Cisse's national team and are both recognised as superstars on the world stage.
Both have become faces of African football and are helping inspire the next generation of Senegalese talent to follow their dreams in Europe.
Coincidentally, both made their senior bow at Metz where they shared the dressing room together in the 2011/12 season.
Mane would then divert to Red Bull Salzburg in Austria while Koulibaly moved on to Genk in Belgium.
Now, they have a unique chance to reunite at club level at Liverpool.
