Del Piero struggles to find positives in Juventus win
Atalanta were the better team on the day and wasted several chances over the 90 minutes.
"These are three points in an extremely difficult moment for us," Del Piero told Sky Sport Italia. "Not much has changed in terms of performance, though, so the only difference is the points.
"It was important to get a win in this very tough time, even if we didn't exactly shine on the field today.
"This result should at least give us an extra bit of confidence to remain organised and concentrated."
