Firstly, apologies for a pretty long post.
I'm afraid AI can easily become a scapegoat but is he really only one to blame? It's not like he's not to blame for the poor performance of the whole team but IMHO he was placed on a ticking time bomb.
Coach with a pretty low experience - from abroad with nearly no one from his old coaching staff around him. At least give him his old assistant he could relay on!
Also, I've a strange feeling that most of us (including myself) overestimated the strength of our team. Please ask yourself a question how many of our players would find a place in the first 11s of other PL teams (not including newly promoted). Now answer to yourself and be very honest! So, how many?
What AI has got from Blake and other people who're responsible for our transfers is... Pretty much nothing. Mostly rejects from other clubs like Radu from Rome (they kicked him out) or Kluivert who already played in few leagues and couldn't find a permanent place. On the top of that trying to copy Brighton without a good scouting team behind and buying a very expensive players like Traore (I still recon he's a good player but completely not suitable for PL, good technically player but no physical attributes at all! Should stay in Italy.) is not going to go well without already fully established PL squad. Another one is Dango who might be on day a good player but not ready for PL yet as well. Then we can go through all the injured players who cost as a lot of money to the last one which no one probably understands - Sinisterra for Anthony who plays only for his national team instead for us. Why? The only two good transfers would be Aarons and Kerketz but again should they be the only choice we've got and relay for whole season on? I'd like to also add Kelly on the top of that who will probably go for free to Tottenham at the end of the season, unless we've a gentleman's agreement with him and have a new contact prepared but trying to avoid FFP punishment. Speaking about Brighton they would probably bought much cheaper and even better players for what we spent. Also, what they normally do perfectly is loaning these new young talents for 1-2 seasons, for instance to Belgium to make sure they're ready for PL before they come back.
Another issue is lack of strong characters in our team and it looks like a lot of them have no heart to play for the club! Are they really listening to AI? Would they listen to other coach for longer period?
I know we all love Brooksy but, unfortunately he's just a shadow of the player he was (not his fault and fingers crossed he'll come back to previous form). Our arguably most suitable player who always gives at least 100% on the pitch is probably Christie. Again, he's got heart to play but is he a really "PL standard/quality player"? He can't even shoot from 16 yards as his every single shot looks like a pass to GK.
Btw. not sure what happened to Neto but did we managed to improve any GK at all? I think Boruc said once, that he had a better and harder GK trainings in Polish league, so take whatever you like from it.
We could go more and more into details but as long as we (Bill where're you now?) don't clean the mess from behind the scenes we'll go backwards instead of going forward.
