The Mirror reports if he does make the move to Merseyside, Saints midfielder Mario Lemina will become the seventh player to swap St Mary's for Anfield since the south coast club went into administration back in 2009.
The six players to have already moved between the clubs since then have cost Liverpool a massive £166.5m in transfer fees.
That's almost five times more than the Saints paid for those same players.
The then League One club cost Markus Liebherr a reported £15m. Since then the Saints have spent a reported £274.5m on new players.
They've also brought in £300m in player sales, though that includes the money paid by Liverpool.
If you remove those sales it works out at £129.7m from player sales with a £144.8m net spend.
