I think he was brought in to convince Quag that he is no longer needed. Initially the case was 1 striker in if 1 goes out, so Quag was staying put; then it became Osvaldo comes in regardless of whether Quag goes or not, hoping that Quag leaves once Osvaldo comes, Quag still refused. that's my theory ofcourse as only club insiders know why he was brought in despite being so mediocre.
Our counter-attacking is just such a glaring weakness. Genoa is just throwing bodies at us and every time we can break the pressure we try to slow the game down instead of sprinting forward.
