Can someone clear up something about training

When you select what coaches to train what, does the number of coaches training matter, or is it all about the rating?

So is it better to have a few people training 3 stars or one guy training 4 and a half stars?

1 guy with 4 and a half. Then if the workload is too high you can add another coach with a lesser rating to help out but the quality of training will stay the same as the highest coaches rating

As said above, one guy on 4.5 stars is better, but it helps to have additional coaches to lighten the workload. I like to have one very good coach assigned to each category (minimum 4 stars) and then I have a couple of other coaches who are not very good (usually ex players who I can't bear to let go of) doing 2 or 3 assignments each, just to support the main guy. This ensures that all the categories are on a light workload.

1 guy on 4 stars is better than 2 on 3 stars.

Ideally I usually like to get one coach per training area, then have my Assistant Manager help out on all of them. So I have expertise in each area and also manpower.

Might not make any actual difference but I like to make him feel useful

get a good coach for the rating, and then lower wage coaches for the workload.

Also good to checked who is training what in your youth squad by accessing training on youth tab. I totaly forgot about this until recently. Never really matter to my side though, as all my youth players were poor and all my coaches were on light work load.
