After beating Napoli to move into second place in the Serie A standings last weekend, Inter Milan faces another direct rival in fourth-placed Lazio on Saturday.
Inter has impressed against the top teams this season, also beating defending champion and leader Juventus.
It's the teams down the table it has struggled and dropped points against. Inter President Massimo Moratti admits "maybe there has been a bit less concentration" in those games.
Inter comes into the match looking to extend its winning streak to three matches in Serie A, but Lazio is also in form and is unbeaten in its last five league matches.
If Inter slips up, Juventus can extend its four-point lead at the top of the standings when it takes on Atalanta a day later.
