Luis Enrique\'s side suffered a setback on Sunday when they were thumped by Juventus but Willie Duncan is backing them to bounce back against Delio Rossi\'s men.Roma will look to cast off the disappointment of a 4-0 thumping at the hands of league leaders Juventus when they welcome relegation-haunted Fiorentina to the Stadio Olimpico on Wednesday night.The home side\'s hopes of beating city rivals Lazio to third place in Serie A and qualifying for next season’s Champions League were dealt a hammer blow at the weekend as they crashed to defeat against Juventus.Luis Enrique’s side’s misery was compounded by the loss of goalkeeper Maarten Stekelenburg who, incredibly, was shown his second red card in just seven matches as Roma were soundly beaten.Nevertheless, Bet365 chalk Enrique’s men up as strong favourites at 8/13 (1.62) to shrug off Sunday’s disappointment in style with victory over Fiorentina.la Viola’s survival hopes were boosted as Delio Rossi’s men produced a solid performance to frustrate Inter and secure a precious home point on Sunday.This assignment, though, looks far tougher and that is reflected by Bet365’s 9/2 (5.50) quote for an away win here while the draw is marked up as an 11/4 (3.75) chance by the same firm.Argentine-born Italian striker Pablo Osvaldo has been a big hit at Roma since joining the club from Espanyol in the summer. Osvaldo has an impressive 11 goals to his name so far in his debut season with the Giallorossi and he is a 4/1 (5.0) chance with Bet365 to add to that tally with the opening goal here.Fiorentina have struggled in front of goal this term, having netted less than one per game on average and they will depend heavily on Montenegro striker Stevan Jovetic to fire them to victory. Jovetic can be backed at 8/1 (9.0) to open the scoring on Wednesday.Roma have been mighty impressive at home this term, losing just three of their 16 fixtures there to date and the 6/5 (2.20) quote from Bet365 for Luis Enrique’s men to lead at half-time is a superb piece of value and should be backed accordingly.
