Francesco Totti sent Roma in the lead, but in stoppages Brazilian ace Cicinho scored an own goal and levelled the scores.
Spalletti said: “Bologna tried to leapfrog the midfield and at the end we did it all by ourselves. We did what we had to and nothing more, so it was sufficient as performances go.”
Roma fans expected their side to win following the 3-1 Champions League triumph over Chelsea on Tuesday.
Spalletti continued: “After the win over Chelsea it was only normal we wouldn’t be particularly sharp. We needed to push with the enthusiasm from that success, but I don’t have many players in good shape and we must accept the 1-1.
“We had difficulties imposing our style of play, but once we took the lead it’s not as if the three points would have been undeserved.
“We tried to play the same way we did against Chelsea, but Bologna sat back more and clamped us down.”
