Cagliari were unlucky to lose 1-0 in a friendly test with Partizan Belgrade, as they gear up for the start of the Serie A season.
The Sardinians are still settling in under new Coach Massimo Ficcadenti, as Roberto Donadoni was sacked last month.
They were far more dangerous in the first half with saves denying Nene', Moestafa El Kabir and Lorenzo Ariaudo.
Thiago Ribeiro came on after the break and within 120 seconds had tested the Partizan goalkeeper.
The visitors only threatened in the final stages with Jovancic and he was brought down by Simone Gozzi for a penalty that Babovic converted.
That proved to be the winning goal, as Cagliari paid the price for not taking their chances at the Stadio Sant'Elia.
