Bari coach Giampiero Ventura says Lazio are the real deal after suffering defeat yesterday.
Sergio Floccari and Hernanes struck for the Serie A leaders in their 2-0 win.
"I knew Lazio had great quality and tonight they confirmed it," said Ventura.
"Our goalkeeper didn't have to make a save. They had two half-chances and turned them both into goals. That is a sign of great quality.
"We read the first half very well, but after the break those two goals in quick succession knocked the wind out of our sails.
"Compliments to Lazio, but this game could've so easily finished another way. They are a competitive side with important players who are prepared to sacrifice themselves for the team.
"Last season their difficulties were an anomaly. You can see that their mentality has changed."
