Without going back to the books I couldn't tell you what would be the ideal to eat, but you may find slower releasing carbs. get you further through the game...those that are found in porridge or whole grain cereals. Sugary or refined cereals are likely just to give you an initial energy boost.

I used to play a lot of rugby on a sunday and found that pasta (often with tuna) kept me going longer through a game before fatigue set in...that or a banana on some porridge.

May be take note of what you eat / drink / how active you are on a daily basis and compare the 2 times of day you play. You may find vast differences in what you eat / drink on say mon / tues prior to playing wed., compared to fri / sat prior to playing on sun.
