Juventus maintained its unbeaten run this season but fell behind AC Milan in the Italian League title race following a 1-1 draw at Bologna on Wednesday.
Juventus failed to make the most of its game in hand on the champion and now trails Milan by two points with 12 matches left.
Veteran captain Marco di Vaio gave the host a 17th minute lead but Montenegro forward Mirko Vucinic equalised just before the hour mark.
Juventus has not lost in 26 league games this season — and 29 matches including the Italian Cup — but it has drawn exactly half of those.
It was its third draw in a row and fifth in six games, and that is the reason it is looking up at Milan rather than down.
Had it won, Juventus would have gone above Milan due to its better head-to-head record.
Once again the Turin giant proved lacking in attack as it failed to put Bologna under sustained pressure, although its makeshift centre-back pairing — including full-back Martin Caceres as both Andrea Barzagli and Giorgio Chiellini were injured — had a largely quiet night.
That was until Leonardo Bonucci was dismissed six minutes from time for a second booking meaning that if Juventus doesn't get one of Barzagli or Chiellini back this weekend, it will have no specialist centre-halves against Genoa.
In other games, a Sebastian Giovinco penalty three minutes from time earned Parma a 2-2 draw at home to Fiorentina while Cesena moved off the bottom following a goalless draw at home to Catania.
Bologna 1 (di Vaio 17) drew with Juventus 1 (Vucinic 59); Cesena 0 drew with Catania 0; Parma 2 (Okaka 28, Giovinco 87-pen) drew with Fiorentina 2 (Nastasic 60, Cerci 71). — Agencies
