Leonardo Bonucci produced the only goal of the game.
"We were coming off a period that wasn't great, so needed to give a sense of consistency to our results. I only celebrate when you win the match, otherwise it's meaningless," Gattuso told Sky Sport Italia.
“We played a great game for 70 minutes, but then made far too many mistakes and risked throwing it all away. We ran so many risks at the end.
“I make my decisions based on how the lads train midweek and the desire to win. It's not just about fitness levels, but whoever deserves a place will play in my team.
“I am very satisfied and happy with the way the lads have worked and from the first day they have been ready to do anything I asked.
“We are a team with a lot of quality, but must also work hard and ensure we don't get caught out on the counter."
