The Bianconeri fell 2-1 at home to Catania on a day that was already tense with eggs thrown at the team bus and protests in the stands.
The coach said: "The same disappointment our fans feel now is also in the locker room and the corridors of the club. We cannot deny the results haven't been up to the standard of this club and we're going through a tough time.
"It's a period when things keep going wrong for us, we're in the thick of the storm, but if we remain united I think we can get out of here. I like sailing and will not abandon the ship."
Juve have gathered just 18 points in last 13 rounds and in total have six fewer than at this stage last season.
"If I have to analyse and say what the problem is, I certainly wouldn't tell it to the media. Besides, if I'd found there was just one problem then we would already have resolved the issue," said the Coach.
"It's not just one problem, it's a series of things coming together in the last three months. We had done very well at the start. We know we're not doing well, but I don't think you can blame just one element.
"I don't think we will go on to the transfer market. Diego and Felipe Melo are top players and certainly not the sole issues in this team."
