Yeh I agree 100%. Some people believe that the majority of the issues are down to the players and that's fine, but in my opinion the majority of it is down to the coach. Obviously some players are more naturally talented than others that goes without saying but I think a good manager that can motivate his players and play in a certain system always improves his players and gets the best out of them.
There's so many players that would be seen as average if they were in our team playing under ten hag, I'm specifically talking about players that are seen as good/great in teams that are above us. Take Man City for example, players like Ake, akanji, doku, kovacic, these aren't (or at least weren't) seen as great players until they went to Man City under pep. I think they'd have been terrible for us and they wouldn't be any better than what we have. Same goes for oh I dunno, havertz, martinelli, white, gakpo, jones, elliot. These are all just 'good' players that are seen as better than ours because of their managers. This isn't me saying our squad is better than the top 3, I still think it's slightly worse but again, there's not huge amounts in it, we're only as good as our manager in my opinion.
Same goes for the Newcastle, spurs, chelsea and Villa squads, don't think there's much in it at all. I think if you swapped emery for ten hag and kept the same players, we'd definitely finish above Villa for example.
It is definitely hard to see it because like I said we've been crap for ages, and Villa or whoever have obviously been really good for the last few years, but I think that's 100% down to coaching, and again as I said before I'll be the first to admit I was wrong about the players if at the end of next season the players still can't play the way amorim wants and gets us up the table, but until then I'm gonna remain optimistic and I think we're gonna be really good (still obviously need some ins and outs if we're talking about winning the league, but top 4 is definitely something we're good enough for)
