Well, I've started a new career in fm21 unemployed, but immediately accepted an offer from Ipswich town in sky bet league one ... I was planning to use 4-4-2 formation, but during pre-season friendlies I was experimenting with some variations which led me to 4-1-3-2 with two wide midfielders with inverted winger roles ! Suddenly during a match it turned to 4-1-1-4 with flat four defenders (wing backs on support), one defensive midfielder (halfback), one centeral midfielder (deep lying/advanced playmaker on support), two inverted wingers as regular starters (left on support and right on attack duty) and finally two forwards (deep lying forward on support, pressing forward on attack duty or advanced forward based on player who starts the match) !
In 7 matches, we grabbed 6 wins and only 1 draw, with GF-GA stats 15-5 ! I'm making some adjusment during the match to send more players forward if we need a goal and opposite, if we need to protect the lead ! I don't know what can I do during my first season without any signing cause the club has no money ! But it is interesting in attacking phase as every adjusment that I'm making during a game, open new doors for my players to put intense pressure on opponent !
I will update this message if you are interested !
