The 69-year-old is regarded as one of Italy's most innovative coaches and his decision to introduce the 4-2-4 formation he used in his club career was initially greeted with mild curiosity by the fans and media alike.
That turned to apprehension when he deployed the system in their crucial Group G qualifier away to Spain last Saturday which saw Italy overrun and outclassed in a 3-0 defeat.
Undeterred, Ventura stuck with it on Tuesday, fielding Marco Verratti and Daniele De Rossi in the centre of midfield, Antonio Candreva and Lorenzo Insigne as wide attackers and Ciro Immobile and Andrea Belotti in the centre of the forward line.
But, with little movement from the strikers, Italy produced a sluggish first-half display and were jeered off at halftime as they failed to make any inroads into the packed Israel defence.
They improved enough after the break to secure the three points but not to convince the public or the media that the system was working.
Italy remained second in the table and, unless leaders Spain suffer an unexpected slip-up in their final two games, their fate is now likely to be determined over a treacherous and nerve-wracking two-leg playoff in October.
There is even talk of Italy failing to qualify for the World Cup for the first time since 1958.
NO PATIENCE
Italy's veteran goalkeeper Gianluigi Buffon said the supporters did not have the patience for a slow build-up.
"Possession of the ball is not valued in Italy. In Spain, when they string 100 passes together, the whole stadium applauds but not here. We ended up rushing some moves to keep the public happy."
Verratti also complained about the whistles from the crowd.
"It's never easy in international football, you just have to look at France who drew with Luxemburg on Monday," he said.
"We are always pessimistic but things in Italy can change overnight. You need one good performance to be considered a phenomenon, but a less good one and they start saying that you shouldn't be playing football."
Ventura, who until last Saturday had been credited with phasing in younger players and bringing down the average age of the team, remained unflustered by the criticism.
"When you don’t score fans can get disappointed, but if you want to be a team you can’t pay attention to applause or jeers," he said.
"The priority was the result and we are happy because we played for 80 minutes' in the opposing half, trying to play the right way."
"It was a small step forward towards what I am convinced we are capable of doing."
