AC Milan go into their home game against Cesena this evening on Multi-TV with their lead over five-time defending champions Inter Milan having been cut to just six points.Lazio and Napoli are just four points adrift of the pacesetters, yet Milan striker Zlatan Ibrahimovic claims he is not worried.Instead, with his club having taken just a single victory in their last four Serie A games and the club deemed to be their biggest threat, rivals Inter, riding a five-match winning streak and with a game in hand, the Swede claims he is having fun."I enjoy the duel with Inter,'' he said. "Like them, we have great experience."It's going to be great battle."With this intensity, there is more motivation for everyone to remain focused and work until the end of the campaign.''For Ibrahimovic, who once played for Inter, the Rossoneri need to only worry about themselves."I know Inter have confidence after their recent victories,'' he said."But we must remain focused and if we do that, we should not fear any of our rivals, including Inter."We need to do our job as best as possible to remain first.''Ibrahimovic is Milan's top scorer with 11 league goals so far.Antonio Cassano could earn his first league start with Milan on Sunday after a solid performance in Thursday's 3-0 triumph over one of his old teams, Bari, in the Coppa Italia.The midweek result allowed Milan to set up a meeting with Sampdoria in the quarter-finals of that competition.Cesena, meanwhile, pushed Inter hard before falling to a 3-2 defeat at the San Siro in midweek.The result followed their 1-0 defeat to Roma and left Massimo Ficcadenti's side just above the bottom three on goal difference.Cesena have won just once on the road this season and will have to overcome the absence of striker Emanuele Giaccherini, who serves a one-match ban.Credit: Multi-TV Sports desk/espn
