Milan: Serie A was hit by yet another controversy on Sunday which left both teams calling for the introduction of goal-line technology.
Palermo were denied a goal in their match at Sampdoria when Michel Morganella`s shot struck the underside of the bar and television replays showed that it crossed the line before bouncing out.
However, even though the goal-line assistant was well-placed, the referee played on and the match ended 1-1.
Even Sampdoria coach Sinisa Mihajlovic agreed that the goal should have been given.
"We have to be sincere, it was obvious (that it was a goal)," he told reporters. "We don`t usually talk about referees, but one of the things that needs to be done is to adopt goal-line technology."
Palermo coach Giuseppe Iachini said: "The additional linesmen are a help but in these situations it is not easy to tell whether it is a goal or not because of the speed of the ball. Technology could give them a hand."
Earlier this month, AS Roma won 1-0 at Udinese in controversial circumstances after Davide Astori`s header hit the underside of the bar and bounced down.
The goal-line assistant did not award the goal, but was over-ruled by the referee which angered Udinese, even though replays suggested the referee was right.
The most controversial incident was in the 2011/12 top-of-the-table clash between AC Milan and leaders Juventus when officials failed to spot that Sulley Muntari`s header for Milan had crossed the line.
Juve, trailing 1-0, hit back to draw 1-1, keeping them one point behind Milan with a game in hand. They went on to win the title unbeaten.
Serie A has since adopted UEFA`s system of employing extra officials on each goal line and in December, Italian federation president Carlo Tavecchio said he wanted goal-line technology to be used from next season.
However, this still has to be approved by the federation`s executive committee.
"These goal-line officials cost 1.6 million euros ($1.79 million)per year which in three years means nearly 5 million euros," said Palermo`s outspoken president Maurizio Zamparini. "That would be enough to equip practically every (Serie A) club with the technology."
