Spalletti said: “When a team wins, it is the best medicine to recreate a bit of enthusiasm. We need enthusiasm and consequently I am convinced that when things start going right, we will get into our stride.”
They were trailing 1-0 in Bordeaux even after Carlos Henrique saw red for elbowing Simone Perrotta on 37 minutes, but after Vucinic's header it was a totally different match.
“We were static in the first half, but once we got the equaliser it all changed and I was glad to see that reaction.
“This is more important than just the three points. We don't have players who are battlers, as ours are more based on technique and quality. In general this sort of player needs the support of an atmosphere.
“Things were not going well for us recently and unless we can get that sense of calm, then we make a bad impression and can't do even the simplest things.
“Vucinic's goal totally changed the game. The lads felt they had a chance of making it and the enthusiasm welled up immediately.
“You could see psychologically they were transformed, felt free to pass the ball around and run into space. It was a decisive moment.”
Julio Baptista was the other hero, bagging a brace after he came off the bench, making his comeback from a thigh strain.
“Baptista arrived at the end of the transfer window, went off for international duty and then had an injury, so he still needs time to settle in to Roma's way of doing things,” added Spalletti.
“I like that he can play as a centre-forward or out wide, has power and quality. These goals will help him to make the breakthrough.”
