Inter Milan chairman is worried that manager Jose Mourinho could make a 'volcanic' decision and leave the club by the end of the season. Mourinho, who repeatedly revealed his dissatisfaction with coaching in Italy, said he will decide on his future after the Champions League final with Bayern Munich. "It is hard to predict what such a 'volcanic' character will do. We don't know what he will do, really," Moratti told Italian radio station Anch'io. "It is either something which will really surprise us, or something which we unfortunately expect - a future not at Inter, but abroad." Inter are on course to win the treble if they beat Bayern in Madrid on May 22nd, as the Bavarians are also double champions in Germany.
