Hi,i see the training but one thing i don't understand why ther is not the time of the session and how big is the field?

What session in particular are you looking at? If the size is not specified you can usually decide on how the big the area should be by considering the level of your players, how hard you would like the drill to be and what do you want your players to take from the session? Unless you are designing your session to correct a specific problem in your team (poor shooting for example) I wouldn't use one drill for any longer than 30 minutes (maximum) as this will lead to your players getting bored and not concentrating on the drill.

Am not that sure yet.... I will be in touch..
