Lazio president Claudio Lotito has set themselves a Champions League target.
Lazio currently sit in third place.
"My congratulations go to the staff and the lads for their excellent approach to the game," said Lotito after a 3-1 win away to Cagliari.
"We produced good quality football, showing consistency and determination in a journey that has seen us seal a seventh straight victory.
"This is an important result which gives us more motivation for the future, new certainties on the potential of this group and the real margins of improvement they still have.
"We will defend third place to the bitter end. Where our legs won't take us, the heart and support of the Biancoceleste fans will."
