Mino Raiola told Corriere della Sera: "At the top level yes [it is his last chance]. Either it works here or it's a bust. If it goes wrong? Mario is 24 years old. He no longer has the alibi of his age.
"Mario played well for six or seven months, giving a decisive push for them to enter the Champions League. But then you could see he is not ready to be a leader. Will he ever be a leader? It's not mandatory that every player has to be a leader.
"Liverpool have Steven Gerrard. There Mario will be protected and can give his best. Now it's up to him. Another flop is inadvisable. Not everyone is born to be a leader and a good striker is not always a leader either."
Raiola also indicated that the transfer will be completed on Monday or Tuesday.
