FC Dallas have superbly executed the 4-3-3 formation in the early part of the 2020 MLS season. In all last season, Dallas used some type of 4-3-3 formation in all but six of their MLS games. This included the 6-0 thumping of Sporting Kansas City.
This season, Luchi Gonzalez has again leaned on the 4-3-3. His team have opened the season with a 2-0 shutout win against the Philadelphia Union and a 2-2 home draw against the Montreal Impact.
The Impact utilized a back-three-based formation which frequently shifted into a back five when defending deep.
