I meant play 4 at the back so 2 DC to handle his 1 ST and push the fullbacks to support your attack wingers. Since after you changed to 4-1-3-1-1 both team's fullbacks had minimum use and i'm sure his fullbacks are not pushing up to attack either. You changed to a formation exactly same as his so it didn't really give you any advantage tactically because you just went man for man. You would had more success if you ordered your players to use attacking, short passing causing them to move forward a little more giving you more space instead with normal mentality they will stick to their position and it's very congested. If you feel it's too dangerous to attack at that point of the game 4 diamond narrow would be better because the team would be more balanced. Your 2 MC would totally control midfield despite being outnumbered because they are better and with mixed passing they don't need to hold the ball or play quick short passes. I played 4-1-3-1-1 a few times to fit my best players using short passing controlling possession well but I lacked firepower as you know its not an attacking formation. Why he scored? I don't exactly know the correct answer but the game is calculated on numbers and probabilities I would think nearing the end your DMC was more tired than his since yours had to work all game and his just started to get pressure. I don't know how he scored. A long shot? A set piece? Either way, you set a difficult order for your own team when clearly the formation you used should be short passing through the middle. If you feel just because you are better on paper and must win then why need to play the match? Should just compare squads and decide winners right? Don't be angry because I would be dissappointed to win by less than 2 goals as well but one day you'll win against someone better than you by more would you know why? Just look back and see why the result came out like that and avoid in the future bro. Invest in wall defenders and arial defenders as long as corner and freekickers bro. Since the game is calculated on probabilities you have better chance to win if you possess all the posibilities. I had many hard games and it came to set pieces. Oh..and next time you need to protect the score line, the last 15 should be defensive minded bro. That and hard tackling, short passing, focus to the flanks....because if you lose ball in flanks, its harder for them to score.
