4-3-3 wide v2 This will probably be the standard variant (not to confuse with the mentality setting) you set up at the start of most games. High d-line, quick and short passes
4-3-3 wide v2 defensive Similar to the standard v2 but obviously more defensive. You can use this to start a game against stronger opponents. D-line not that high, passes a bit slower and longer
4-3-3 wide v2 rainy To start on a very wet and muddy pitch. Generally a bit slower passing play and longer passes. Generally slower and longer passing style
4-3-3 wide v2 rainy defensive Same as rainy but more defensive. deeper d-line, longer and slower passing style
