MILAN, August 23 (Supercoppa) - Internazionale coach Jose Mourinho does not believe Roma, his team's opponents in Sunday's Italian Supercoppa, will be affected by the loss of Francesco Totti - but insists they will miss former winger Mancini. The Brazilian winger became Mourinho's first signing at Inter when he made the switch from the Italian capital to the San Siro for 13 million euros in July. He was one of Roma's best players last season, as the Giallorossi pushed Inter all the way in the race for the Scudetto and beat the Nerazzurri in the final of the Coppa Italia. Roma captain Totti, who is yet to recover following knee surgery in April, is likely to sit out the game despite being named in the squad. But Mourinho believes the loss of Mancini is what will hurt Roma the most. 'Totti is a fantastic player, but things won't change much just because he can't be there from the first minute (of the season),' he told a press conference on Saturday. 'Roma have been working for many years with the same squad, it is not a drama if they lose a single player. Also, last year they were in the race for the Scudetto until the last day. 'But football is all about titles, if it wasn't that way we would be in the garden playing with the children. And the title was won by Inter, even if Roma were stronger in the cup. 'Today, however, I told my team today that Roma are not the same without Mancini.' The rivalry between Roma and Inter has grown over the past season as the capital club have emerged as the main rivals to the Milan side's recent dominance of Italian football. While the Supercoppa may not be the most prestigious title the two sides will compete for this season, Mourinho insists he is keen to win a hat-trick of trophies. 'The Supercoppa is obviously not the Champions League final, nor is it the final of a national cup, but it's a beautiful game to play,' he said. 'I've won it in Portugal and in England, and I lost it in England too, and if possible I want to win this one at the first time of asking.' Roma come into the game following a difficult week for the club. As well as missing their captain, the Serie A runners-up go into the game still shaken by the death of club president Franco Sensi last Sunday. The club's longest serving - and most successful - president had been unwell for a long period and had spent the past few weeks in the Gemelli Polyclinic Hospital in Rome undergoing treatment for respiratory problems. New signing Julio Baptista, who joined the capital club five days before the president passed away, never met Sensi. However he still believes a win over Inter would be a fitting tribute. 'With determination we will win for Sensi,' he said. 'The passing away of a person like him is a always sad situation. I hope that the team wins to make him happy. 'He will be watching us. And I am ready.'
