Yes of course it would be a risk but pretty well any appointment is a risk. Koeman on paper carried very little risk but he proved to be a disaster. Allardyce is perhaps the least risky, with defence minded percentage football guaranteeing a mid table finish but with no prospect of winning anything and crushing tedium for those watching. You can take calculated risks and if Arteta is interested in the job then Brands and Moshiri should be grilling him to find out exactly how he would have his team play tactically, would he be a flexible manager ( unlike Silva with his obsession with 4231), who would he bring with him, how would he set up the present Everton team based on the present squad? If, as I hope, he is a manager who will play in a progressive style that will emulate City's style of play under Guardiola then the rewards could be fantastic. In life the people who succeed are those who take opportunities when they arise. Silva's time is over so the opportunity is there. If Arteta is interested then I for one hope that we take the risk.
