i was wondering before when your scout get a report for the next match why he doesn't tell you what kind of pitch they have. Like one which will suit wide players or not?
The pitch at x is narrow and wide players will struggle to make an impact.
The pitch at y is long which will favor teams playing a direct style. If defenders push up there will be space for the quicker players to take advantage of.
Plus you can always go to opposition team information screen and check the exact dimensions of the pitch.
Is your scout newly signed and somewhat lacks in...well, quality ?. Then this can happen. In time, he will provide you with information regarding favoured width to be used
