The Football Season

The football season is a bit different to what you are probably used to. Pre-season usually starts at the beginning to middle of August and the season finishes late November depending on how well you do. You train every day or almost every day and usually play 2 games a week.
In the off season you will train indoors, and when its warmer outside again. This is to keep you fit and ready for a few games or tournament in about April time.
