At the end of the day we all know Sarri will be gone come the seasons end as Chelsea have ambition.
People will argue we are everton they are chelsea however the principle applies - if you appoint mediocrity and accept mediocrity then you become and remain mediocre.
Moshiri needs to do what he hasnt done since he joined the club and undertake (alongside Brands) a proper recruitment policy and interview a wide range of managers who have a track record of either league or trophy success in competitive leagues (england, spain, germany, italy).
If we keep this fella we'll at best finish bottom half next season or at worst be in a relegation scrap. If some fans are happy with that then fair enough but I imagine a fair few will sack it off having already experienced the past couple of disaster seasons.
