Juventus midfielder Claudio Marchisio says they're wary of a rapidly improving Lazio.
The two will meet in the Coppa Italia final and also in Serie A before the end of the season.
"The first time we played them [a 3-0 win in November] Lazio were not as strong as they are now," Marchisio to Juve TV.
"They're a team who have great individual and collective quality, and they have a great Coach [Stefano] Pioli who started this year with criticism but has proven his worth.
"So they won't be easy games, and we'll have to be very careful. That said, we'll have time [to think about those games], we have more important goals coming up, and we must think about them.
"However, they're definitely a team to be reckoned with, because even at this point in the season they'll definitely be fresher [having not played in Europe]."
