Second place is not good enough for Inter Milan president Massimo Moratti as the Nerazzurri look to close the gap on Serie A leaders Juventus with victory at Lazio.
Inter have recovered from a slight wobble to win two consecutive games, including a decisive 2-1 victory over title rivals Napoli, but Moratti is still worried about the current four-point gap on Juve.
He told Gazzetta.it: "Winning the next two league games could be enough for us to have a happy Christmas. But they won't be easy.
"Here at Inter we need to keep winning everything over the coming months so we can have a splendid summer.
"We're doing what I think is within our power and we will see if we are better than all the other teams come the end of the season.
"(Head coach) Andrea Stramaccioni has proved that he can handle the situation very well and he has proved to be more mature than I expected he would be."
Lazio are unbeaten in five, taking 11 points from the last 15 on offer to move into fourth place and Champions League contention.
Meanwhile, third-placed Napoli are hoping to bounce back from defeat at Inter with a positive result against Bologna, which could see them leapfrog Inter into second depending on Saturday's result.
Azzurri striker Lorenzo Insigne said: "We are focused on the championship and taking it match by match.
"We did our best in Milan and we will make up for what happened against Bologna. Even though we were beaten at the San Siro, we played a great game."
