Inter Milan left it late to move to the top of the table with a 2-1 win over in-form Udinese.
Dejan Stankovic put the Nerazzurri ahead in the 22nd minute, but Antonio Di Natale equalised within five minutes.
Both sides had chances to win an entertaining game before Wesley Sneijder struck deep in stoppage time to break Udinese's hearts and take Inter one point clear of Sampdoria at the top of the table.
"Sneijder's goal was what the team deserved," said Inter Milan coach Jose Mourinho.
"The team played well. We had lots of chances in the match, especially since we had the injury to Diego Milito [replaced in the 25th minute] who is such an important player for us.
Kutuzov comes close
Bari and Catania shared the points in a disappointing encounter at the Stadio San Nicola. Chances were at a premium as the two sides struggled on a pitch that has received criticism this season.
The closest either side came to scoring was when Vitali Kutuzov hit the post for Bari in the first half of a tight game.
