Top-flight, 4 star or over teams, start to get to the point where they're so physically dominant that unless you're a FIFA expert, you could be going to get manhandled by them should you chance a weaker squad out, whatever. They'll win more 50/50 balls, have more corners, breakaways, everything, to the point it's ridiculous. It will require some feel to find out how bad of a team it is possible to roll out there, but you'll start to get a practice it. But make use of your best team to be a limited method to obtain bullets that you just only set off within the most critical circumstances. Bronze players are cheap and replaceable, when you can win together you save a lot of coins.
Thankfully, you don't have to build your team almost every time you practice on a match for various quality opponents. You'll have multiple squads, and I generally like to have a squad with just bronze players, silver and bronze players, and then a gold-quality team.
You should use they builder to make this method much easier, but I generally recommend going into and experimenting while using roster additionally beyond that. You might like to switch around your bench and reserves to ensure that you aren't wasting contracts on players just lounging around.
