Inter Milan President Massimo Moratti believes that Swedish striker Zlatan Ibrahimovic has been influential to the Nerazzuri's title race this season. The 26-year-old has been the main man for Roberto Mancini's team this season, scoring 15 Serie A goals to help his team enjoy a historic campaign without suffering any defeats. "He is a sensational player and he's decisive in each match," Moratti was quoted by Sky Sports on Friday. "Let's hope he will continue in this way, because he would deserve a similar award." Ibrahimovic joined Inter for 24 million Euros from relegated Juventus after the infamous match-fixing scandal in the summer. Inter are on course of a second successive Serie A triumph as they lead second-placed Roma by a massive 18-point gap, but the Italian billionaire insists that the match against Roma is important to ensure the club's supremacy. "Surely the match against Roma will be important, because they continue to play in a good way," he added. "We must continue with this professionalism, and with this pleasure, because it seems to me that players enjoy themselves when they play."
