Inter Milan Chairman Massimo Moratti has denied any backroom clash with coach Roberto Mancini following the team's defeat against Juventus last Sunday. "It's all rubbish. Despite what you say in your reports there has been nothing, these are all things to deny but I do not have the patience to do so," Moratti told Corriere dello Sport. Reports in the Italian press claimed that both men were involved in a tough talk after the defeat and that the players backed their coach. Mancini had previously announced that he will quit Inter at the end of the season following their Champions League exit but 24 hours later he made a U-turn his decision. "I hope these rumors do not have an influence on Saturday's performance because we have a big game against Lazio," added the Inter supremo. Inter will have a tough battle on Sunday against Lazio in day 31 of the Serie A. The Nerazzurri have a four-point lead on top of the Italian standings.
