Eh?
Ferrari only came on loan & hardly played but when called on he mostly did well. IIRC he had one bad game on his debut away to Arsenal, played out of position at full back. We've had shitloads of players worse than him since the 90's.
Exaggerating for comedy effect, but I don't have good memories of him. Perhaps being harsh on him, he's far too closely linked to the Kroldrup era for my liking.
