I think fans dislike Emanalo is because he came on the scene after Jose was sacked the first time & was promoted as first team coach when Grant was "in charge".
This for a man who at the time had no coaching badges or experience apart from being in charge of a girls U12 team.
Since then we've had success but also seen managers unfairly sacked, like Carlo.
None of us will ever know for sure what goes on behind the scenes, what i will say is though our transfer policy the last 6/7 years has been baffling at times, particularly with us selling & buying forwards.
We bought Torres when he wasnt needed & sacrificed the PL title for 5 years while accommodating a non scoring forward, this after only a year of us winning the double while scoring goals for fun-103, with Drogba, Anelka, Kalou, Sturridge, as our forwards.
When Jose returned he also persevered with Torres with us missing out on another title, the following season Torres was sold & we won the title.
In recent years we've persevered with going in to campaigns very light up front & made some strange signings, Eto, Ba, Falco, Pato to name a few.
Now whether Emanalo is to blame for this no one knows but what i will say is someone behind the scenes is making these deceisions i cant be the only one to think that no experienced manager would be happy to have a squad so light up front? last season it was lucky Costa didnt get injured because if he had we'd have to have relied on Michy Batshuayi, a player who'd hardly played.
Here we are again another season going in to a campaign light up front, hopefully Morata will become a great goalscorer for us but should anything happen like he struggles for form or gets injured we're back to only having Michy Batshuayi to call upon, that isnt good enough for a club of our size & with also CL football this season.
Someone is calling the shots behind the scenes, maybe its only Roman? maybe i'm in a time warp but personally i'd like our managers to be allowed to manage with no interference from behind.
