Barcelona would be happy to have the first leg of this game by 4-1 as they play Valencia at the weekend and would not want to over-exert themselves in this game. They needed two own goals to open the scoring at Camp Nou but they would not mind as long as it brought them the win.
Roma failed to recover from their loss to Barcelona in the first leg and they went on to lose their very next game 2-0 at home to Fiorentina. They play SS Lazio next after this game and they would be looking to get a good result here to keep their spirit up before that derby.
Barcelona won their next match at the weekend 3-1 against Leganes and they would be in the best of spirit especially with Lionel Messi back. They are now unbeaten in their last 19 games since they lost to Espanyol in Copa Del Rey.
Barca have not lost a Champions League game since they lost to Juventus last season. Roma have kept four clean sheets at home this season and all but one of their home Champions League games have ended in under 2.5 goals. Barcelona have also seen less than 2.5 goals scored in all of their away Champions League games this season.
