The ex-Liverpool defender tweeted, then quickly deleted a message of frustration toward the Reds' left back.
Former Liverpool defender Jamie Carragher has hit out at Alberto Moreno and urged the club to sign a "new f***ing left back" after the Spaniard's performance in the Europa League final against Sevilla.
Moreno was at fault for Kevin Gameiro's equalizer moments into the second half in Basel and struggled throughout versus his former side as it won 3-1.
And Carragher - who was pictured in Switzerland earlier in the day - took to Twitter to lambast the fullback and urge both Jurgen Klopp and the club's transfer committee to find a replacement this summer.
