Sevilla salute boys from Brazil
Fabiano and Renato's goals also put the Spaniards in early control of their pool after rivals Stuttgart and Rangers drew 1-1.
The Romanians, playing in their first UEFA Champions League campaign, were only promoted to the top flight of their domestic league three years ago, and are coached by former Chelsea defender Dan Petrescu. He played in the Steaua Bucharest side which reached the final of this competition in 1989 and he brought all his experience to bear against the former UEFA Cup winners in the first half.
Sevilla, who made the last 16 of the Champions League on their debut two years ago, struggled to make an impression in the early stages, with Fabiano and Diego Capel getting two shots on target. Romanian keeper Giedrius Galamaz was also alert to smartly save a Fabiano free-kick. For the Romanians, Iulian Apostol and Sorin Frunza had half-chances.
Fabiano grabbed two goals in the 4-1 Spanish league win over Real Zaragoza at the weekend and it was the Brazilian who broke the deadlock on the stroke of half-time. Renato broke down the left, pulled the ball back to the edge of the area where Fabiano was waiting to slot home confidently.
Sevilla continued to press and went 2-0 ahead in the 70th minute. Substitute Diego Perotti swung over a corner with Fabiano heading the ball into the path of compatriot Renato to score from close range. In the dying moments, Renato hit the post as Sevilla looked to finish with a real flourish.
