Felipe Melo says Juventus' squad is short of quality.

Melo, himself, has struggled to make an impact since his move from Fiorentina, but insists Juve need more new signings if they're to match Inter Milan.

The Brazilian midfielder told Tuttosport: "A team has to start with a good Coach and now a Coach with experience has arrived and he helps us a lot.

"Now, for example, we watch the videos of our games, through which Zaccheroni makes us understand the mistakes we have made.

"This doesn't mean to say that Ferrara was a bad Coach: I liked him a lot. Anyway, aside from the Coach, we need some other strong players who can make the difference, like Diego and Del Piero, because there is need of five of six players who can make the difference. And hopefully we can win.

"In any case, we will surely do better next season because we won't have the same problems understanding each other."
