Who could Liverpool sign next?
He follows Naby Keita, Fabinho and Xherdan Shaqiri in at Anfield this summer.
Here is an overview of who could be next...
A move for Nabil Fekir would send Liverpool fans into dreamland, and it could happen.
The Reds thought they had signed the Lyon attacker before the World Cup only for it to fall through, BBC Sport reported.
A move could still be resurrected but there are mixed reports on this, and a move could be too expensive for the Reds after signing Alisson.
If they can pull it off, he would be a perfect replacement for Coutinho and Liverpool's wait for silverware could be over.
If Liverpool can't land Fekir, then Paulo Dybala would be an incredible fall-back option.
Juventus need to balance the books after selling Cristiano Ronaldo and Dybala would fetch a big fee.
World Cup finalist Domingoj Vida is reportedly on Liverpool's radar, with Turkish publication Aksam claiming the Reds have made a bid worth £20 million.
It would be a more sensible price for Liverpool to pay if this were to come off, strengthening thei squad without breaking the bank.
Vida would compete with international teammate Dejan Lovren for a spot, or even allow Liverpool added flexbility to play three at the back.
