Inter Milan were jeered off the pitch by their own fans at the San Siro on Friday after their latest humiliation, a 3-0 defeat to lowly Bologna.

This latest defeat, their fifth in six games and also the fifth time in that period they’ve failed to score, came hot on the heels of a home defeat to rock-bottom Novara.

Over those six games Inter have conceded 15 goals, scoring just four times.

This run has badly hit their Champions League chances, leaving them in sixth and six points behind third-placed Lazio, who have played a game less.

To make matters worse they were also leap-frogged by Napoli, who won 3-0 at Fiorentina.

Veteran Marco Di Vaio scored a first half brace within 60 seconds and Robert Acquafresca added insult to injury late on.

It was no less than Inter deserved for another performance devoid of confidence or invention in the final third.

But what really cost them, particularly in view of under-fire coach Claudio Ranieri’s pre-match assertion that they must stop conceding goals, was how catastrophic their defending was.

And yet Inter started in total control of this match as Maicon leapt to meet a corner only to see goalkeeper Jean-Francois Gillet kick away his downward header.

Maicon was then picked out in the box again by Wesley Sneijder but this time he headed wide.

Uruguay forward Diego Forlan was presented with a glorious chance following a defensive mistake by Gillet came out well to block his shot with his feet.

And suddenly Inter went into meltdown as Di Vaio scored twice within a minute from defensive errors.

In the second period Nagatomo set up Forlan but he couldn’t get any power on his shot and Gillet managed to get across to stop the ball crossing the line.

Five minutes from time Ranocchia was again guilty of weak defending leaving Nagatomo with a one-on two and Acquafresca surged past him before finishing low to Julio Cesar’s right.

Edinson Cavani was the two-goal hero for Napoli while Ezequiel Lavezzi added the injury-time cherry on the cake to give Napoli the perfect preparation for their Champions League clash against Chelsea on Tuesday.

Napoli were off to a dream start after just three minutes as Marek Hamsik played in Cavani who fired home.

And they should have had a second when Christian Maggio rose unmarked to meet a corner but his header crashed back off the bar.

In injury time Lavezzi escaped on a break and sent a precise finish inside the post.
