The Italia '90 star was vocal before the tournament about his own country's chances and publicly lambasted Inter Milan's Samuel Eto'o - undoubtedly Cameroon's highest profile player.
However, Milla's fears have largely been proved correct as the Indomitable Lions fell at the first hurdle by failing to navigate their way out of Group E, which included the Netherlands, Denmark and Japan.
Only Ghana's journey to the quarter finals gave African fans something to cheer about in the latter stages, and with an extra qualification place awarded to hosts South Africa, Milla was expecting more from the region's teams.
"It was disappointing," he said. "A lot of people were saying that there would be three African teams in the second round and only Ghana made it, although that was to the quarter-finals.
"I was hoping for more and expecting more, along with better results."
Cameroon's quarter-final finish in 1990 remains unbeaten by any African side, but the French-speaking nation will not be remembering their team's 2010 campaign with such fondness.
"Being eliminated in the first round was, unfortunately, something that could have been foreseen," Milla highlighted.
"The lack of discipline that has been happening over the past three years made the results not a surprise.
"There was a lot of indiscipline within the team and some issues between the players."
Manager Paul Le Guen resigned after his side's early exit, which came after defeats to Japan and Denmark and the Netherlands.
