Udinese climb, Lazio held
Udinese moved into the top half of Serie A thanks to a 2-0 win over Sampdoria at the Stadio Luigi Ferraris, while Bologna and Lazio drew 0-0.
Goals from Danilo and Antonio Di Natale in the first half were enough for Francesco Guidolin's side to take the spoils in Genoa and put five points between the two sides.
Nicola Pozzi had a penalty saved in the second half as Samp failed to mount a fightback and remained just three points above the relegation zone.
Bologna and Lazio shared the spoils at the Stadio Dall'Ara as neither side were able to warm up the fans on a freezing night in the Emilia-Romagna capital.
The home side had the better of the game, and created the better chances, but neither team could break the deadlock.
Lazio ended the game with 10 men after Libor Kozak received a second yellow card five minutes from time, but Bologna still could not find a winner even with an extra man advantage.
