Inter were left fuming after a costly mistake by Juan Luca Sacchi contributed to a 2-2 draw against Monza in Serie A yesterday, and they have lodged a complaint against the referee.

As reported in today’s newspaper edition of Corriere dello Sport, the Nerazzurri’s management team contacted the Italian Referee’s Association (AIA) to vent their fury at Sacchi, after he disallowed a Francesco Acerbi goal in the second half that would have put Inter 3-1 up.

Acerbi bundled in but Sacchi had already blown for a foul on Pablo Mari by Roberto Gagliardini in the build up, only for replays to confirm that the Monza defender had been tripped by teammate Armando Izzo.

As play had been stopped before the ball had crossed the line, VAR were unable to intervene and so the goal was chalked off, leading to a furious reaction from Inter after the game.

The Nerazzurri went on to concede in stoppage time at the U-Power Stadium, but much of the attention was focused on Acerbi’s effort.

It is now expected that Sacchi’s error will lead to him being suspended in the next round of Serie A fixtures.
