Claudio Ranieri felt both Inter and Roma deserved praise for their epic tussle, but strength in depth made the difference.
“We played a very good game and the incidents went against us,” he said of the 5-3 defeat at San Siro.
“Inter deserve compliments for their performance, but so do we, as we reacted and tried to get a difficult situation back on track.
“What we lacked was consistency in the pace of our football. It is a very physical Inter side, so it was the only way to beat them.
“Without taking anything away from my squad, when you come up against a side like Inter, there are differences,” confessed the Giallorossi Coach.
“When they make a change, there are always players who can make the difference. Substitutes are crucial for the result and at the moment we're unable to count on them.
“We'll pay a price for Nicolas Burdisso's red card, as with Philippe Mexes also suspended, we will have an emergency situation at the back.”
Ranieri had said Roma were still in the Scudetto race, but after this result they are now 10 points off leaders Milan and stuck in seventh place with a game in hand.
“We are forced to chase now and it won't be easy. In any case, we have to always give our all until the final whistle.”
