MILAN, Italy - Ferrari should pull out of Formula 1 if historic Monza is axed from the calendar.That is the view of Roberto Maroni, the president of Lombardy, after F1 supremo Bernie Ecclestone's warning this week that even Monza, the historic home of the Italian GP, might not be safe as he looks to scrap "a couple of races" in Europe in favour of "emerging markets".Ecclestone said: "If we do move away from Monza - and I say 'if', because no decision has been taken yet - it would be only for economic reasons."Of course, the quality of the circuit and the organisation could also be better, but that is not the crucial point." ONLY ONE OPTIONMaroni is quoted by La Repubblica: "He (Ecclestone) thinks he's father and master of the world, but he cannot decide such a thing without even consulting with people."If he does (axe Monza), there would only be one thing to do - Ferrari withdraw from the Grand Prix and the F1 circuit," he added.As for whether Lombardy could intervene directly, Maroni confirmed he is "interested in any solution".
