An unfamiliar Fulham side containing debutant Josh Passley and rookies such as Chris David and Muamer Tankovic were almost dumped out by their Sky Bet League One opponents, who played the last 37 minutes with 10 men following Michael Doyle's off-the-ball kick.
"I'm immensely pleased and proud of them, the work rate was the standout," Clough told Press Association Sport.
"It was a great effort with 10 men for that amount of time. It was remarkable to not just contain Fulham in the second half, but to be a threat as well, which was great to see.
"The crowd responded because there was a sense of injustice - from us as well - to some of the decisions."
Both sides were denied penalties with Rodallega and Ryan Flynn apparently fouled in the area only for referee Marriner to wave play on each time.
Clough added: "There was definite contact on Ryan Flynn in the area and at 2-0, even with 10 men, you'd hope to see it through."
