One of the most important aspects of the match day is the warm up, ideally the routine should be uniform and regular each fixture, this ensures that each player knows the process and can focus on the muscle warming and preparation.
Reduce the time spent on warming up on a summer day, as the warmth will help the process. Spend more time on it on a cold day. Another aspect is to blend muscle stretching and football together, ensure your players get a good touch of a ball whilst gradually warming up all of the body.
