There's the 'big 6' and now you can add Newcastle (7), Villa (8), Brighton (9), West Ham (10) as teams any newly promoted teams wont get near over 38 games. These 10 teams have WORLD CLASS players/ managers.
SO 10 teams out of reach.
Then Wolves have top top players like Neto, Cunha, Hwang Etc. Brentford have Toney, Mbeumo, Janelt etc. Palace have Olise, Eze, Anderson, Guehli etc. Forest have MGW, Murillo, Awoniyi, Dominguez etc. Fulham have Palhinha, Leno, Robinson etc and Bournemouth have Solanke, Billing, Scott etc.
The newly promoted teams like Luton, Sheff U and Burnley have no where near this talent and that is why they are firmly in the bottom three.
The 3 recently relegated teams occupy 3 of the top 4 spots in the Championship and it's only an amazing Ipswich team spliting them up. I think this trend is only going to get bigger with FFP.
