Bosses at Ferrari "understand" what went wrong in Melbourne.
Last Friday, Sebastian Vettel met with engineers at the team's Italian headquarters.
Prior to that meeting, the German said: "We have all the tools, all the ingredients, the data makes sense, but we are missing something."
Turrini wrote on his Quotidiano blog that engineers now "understand" what went wrong in Australia.
"I do not know what was understood," he wrote, "but there is no panic among Binotto's boys."
Gian Carlo Minardi, a former F1 team owner and boss, tipped Ferrari to bounce back.
"One swallow doesn't make a spring," he is quoted by Corriere dello Sport. "I am confident that Ferrari will recover.
"Mercedes is obviously the team to beat, but let's allow Ferrari to work."
