Barcelona won the first test without injured player Lionel Messi after winning a deserved 2-0 victory at home to Inter to dominate the second group in the Champions League.
Midfielder Ravinia opened the scoring against a rival who spent the second half of last season after a superb work by Luis Suarez in the 32nd minute.
Spanish left-back Jordi Alba ended a late-second-half break to Inter Milan to end the seven-match winning streak in all competitions for Ernesto Balverde's third straight win in the Champions League.
Barcelona lead Group B with nine points while Inter are second with six points.
If they win the return leg at the San Siro in two weeks, the Catalan side will effectively be placed in the knockout stage of Europe's top club competition.
