Manchester City and Inter Milan's scoreless draw in their Champions League on Wednesday, coupled with Bologna and Shakhtar Donetsk's inability to find the back of the net, marked an uncharacteristically goal-scarce night for Europe's premier club competition.
A mere 13 goals were scored across six matches, contrasting sharply with the previous day's tally of 28, which included Bayern Munich's impressive nine-goal haul.
The occurrence of two goalless draws after just 12 games is a significant deviation from the norm, considering that last season's group stage, now discontinued, witnessed only four such results in 96 matches. The 2022-23 tournament boasted an average of three goals per game.
