Liverpool don’t want to sell Coutinho but the player is keen on a switch to Barcelona.
The Reds have turned down two offers from Barca for the Brazilian.
But with Coutinho having now handed in a formal transfer request, their resolve could weaken.
The People report if Liverpool do sell, Napoli’s Insigne is a potential replacement.
Jurgen Klopp is said to be a big fan of the Italian, who scored 20 goals from midfield last season.
The German manager is said to be furious with Coutinho over the transfer saga.
Coutinho only signed a new contract last season, and said: “I signed this new contract to stay here for a few more years because it’s a great honour for me and it shows my happiness here.”
