Lisandro.
He didn't. No one is saying he is. You are making this up yourself that we are saying he can score 30 goals. In fact, any player we could possibly sign won't score 30 goals. Llorente won't, Jovetic etc wouldn't. No one will unless we sign Falcao, Messi or CR7.
He scored 21 all up in 08-09 season with Udinese.
By saying 1 goal every 92 minutes, it means he is our most effective player and thus should be starting more often if we want more goals from our foward line.
