OK, this is my next match that I will be attending which will be a home game. I know there are different Formations on the pitch. Regarding the Diamond Formation is that the most common set up on the pitch for most matches? Is it the most preferred by managers? The way I see it is and please correct me if i'm wrong is that the Diamond Formation consists of the following :- 2 Centre Backs or Centre Halves - namely JT and Carvalho 2 Full Backs or 1 left back and 1 right back - Ivanovic and Ashley Cole 4 Midfielders - Mikel, Essien, Lamps, and Essien 2 Centre Forwards (Strikers) - Drogba and Anelka This is what I understand we had for the game against Hull and of course it may change for the Burnley game. I think i'm correct in saying and again correct me if i'm wrong, the Centre Backs and Full Backs are essentially there to defend the goal. The midfielders are there to support the Centre Forwards (strikers/scorers) and one of them will provide extra protection to the defence. Again I know that the Strikers aren't the only ones that score, in effect anyone (apart from Petr Cech) can score is that correct? I know Lamps has scored of many occasions and I think i'm correct that JT has too. Do some or all of the players ever switch roles?
