Diego completed a nightmare week for Juventus by ballooning a penalty over the bar in their 3-1 defeat at Bari.

The pressure was on the Bianconeri after the shock 4-1 home defeat to Bayern Munich that knocked them out of the Champions League midweek. All the enthusiasm from beating Inter had evaporated and Ciro Ferrara made tough decisions, benching Alessandro Del Piero and Mauro Camoranesi, but sticking with the disappointing Diego. Momo Sissoko, Giorgio Chiellini and the suspended Felipe Melo were out. Bari had to completely reshuffle their defence as Andrea Ranocchia and Alessandro Parisi sat out bans with Salvatore Masiello, Vitalii Kutuzov, Mariano Donda and Antonio Langella sidelined.

It was freezing in Bari and so sawdust was sprinkled on the goalmouths to stave off ice.

The home side took a shock lead just seven minutes in. They had been more aggressive from the start and Claudio Marchisio was dispossessed in the D by Riccardo Meggiorini, whose volley took a decisive deflection off Tiago Mendes to beat Gigi Buffon.

Coach Ventura was more furious than in the mood for celebrating, as Meggiorini took his shirt off and earned a yellow card.

Jean-Francois Gillet blocked a deflected Diego effort at the near post, then Marchisio combined with Amauri only for the Brazilian to scuff wide.

Bari could've gone 2-0 up on 22 minutes, as Leonardo Bonucci was allowed a free header from a set piece, but nodded over from seven yards.

Juventus survived that scare and immediately afterwards scored the equaliser. Gillet was at full stretch to get his palm to a Diego snapshot, but Trezeguet was there to tap in the loose ball from close range.

Moments later Diego pounced on a poor Diamoutene clearance, but Gillet parried it and caught the Amauri follow-up. Meggiorini drilled wide at the other end and Martin Caceres was fortunate his slip did not allow Rivas to score.

Rivas spread the ball for Meggiorini's shot straight at Buffon, while Amauri soared above the crowd and still couldn't quite get a firm header, then as the move continued Marchisio flashed his effort over the bar.

Just shy of half-time Barreto burst into the box down the left and fell over Fabio Cannavaro's leg, but replays suggest it's very difficult to tell whether the Bari player ran on to the leg or was tripped. The referee pointed to the spot and Barreto sent Buffon the wrong way, having missed two penalties this season.

Straight after the restart Bari had a series of shots charged down in the box, but at the other end another woeful Diamoutene clearance set up Trezeguet from six yards, the strike parried by Gillet's legs at the near post.

There was chaos in the Juve box in this end-to-end match, as an Edgar Alvarez cross found Rivas slip at the back post, then the clearance turned into almost an own goal with deflections until Buffon gathered.

Rivas horribly wasted a counter when it was four Bari players against three defenders, putting the through ball where nobody was ready to make the most of it.

Poulsen smashed wide from distance, then Amauri only glanced his header from Trezeguet's cross. Barreto sprung the offside trap to go totally clear on goal, but Buffon came tearing 20 metres out of his box for a sliding tackle.

Trezeguet knocked down the ball for the unmarked Tiago Mendes to flash a volley across the face of goal. The Portuguese midfielder wasted another golden opportunity by nodding over at the near post. Fabio Grosso replaced Molinaro, who had a right knee problem.

Buffon needed a tricky save to deny a Meggiorini free header from the penalty spot after great work from Kamata.

Within 120 seconds of stepping on to the field, Grosso had earned a penalty for Sergio Almiron's clumsy sliding tackle. That was the first spot-kick Juventus have been awarded in Serie A this season and Diego ballooned it over the bar! It was a horrible effort from the Brazilian who tried to put it into the top corner and completely missed.

The Juventus bench complained to the fourth official that a laser pen from the stands was aimed towards Diego's eyes as he was taking the penalty. Replays do show a green flash across his face.

Mauro Camoranesi replaced Tiago and Nicola Legrottaglie headed a corner inches over the bar. Kamata went on the counter with three against two, but again Bari fumbled the opportunity.

However, from the corner Almiron hit a daisy-cutter that took a deflection along the way to beat Buffon and slip into the far bottom corner of the net. Almiron is a former Juventus player and the corner came out to 20 metres, but the shot hit Amauri along the way.

Moments later Gillet flew to fingertip a Poulsen volley out from under the crossbar, as Juve did not give in. From the corner Amauri nodded over, but to make matters worse Camoranesi pulled up with a suspected thigh strain.

Substitute Sebastian Giovinco tested Gillet a couple of times late on and Amauri's head whistled wide, but Kamata also went close for Bari on the counter.

It should've been 4-1 at the 93rd minute when Kamata went forward and crossed for Alvarez to volley over from six yards at the back post.
