Inter president Massimo Moratti has hit out at the "non-existent" penalty conceded in Sunday's 4-3 defeat by Atalanta and believes it was the turning point in the game.
The Nerazzurri were leading 3-1 with less than 30 minutes to play, but the controversial decision to award the visitors a spot kick sparked a comeback that saw the hosts lose to a 12-minute German Denis hat-trick.
"I’ll only comment on the penalty. A penalty like that truly changes a match. It puts a team in a position in which they feel they don't matter," he told reporters after the game.
"With a nonexistent penalty that goes against you, everyone usually does things in good faith. Do I believe that was done in good faith? No."
The 67-year-old also hinted that Inter's failure to earn a penalty in their 20 outings goes beyond statistical logic.
"I believe 20 or 21 matches have passed since the last time we got a penalty in our favour. I think it’s impossible not to have deserved one in 21 games," he added.
