So finally I've started with 5-4-1 formation and it started ok I was leading 2-0 but then i started to loose goals and it changed to 2-3.
Then I switched to 4-4-1-1 and was able to score for 3-3.
Tomorrow there is a rematch. My team is slightly better but he might have beter CM's.
I need to win it tomorrow on his ground to go into the final.
Can someone help me please with a tactic?
