I have lost 2-1 away in cup semi final,i was playing 4-5-1V and the goal I scored came after I removed the back arrows from my DCs/DMC and made a sub with another ST for my MC and played 4-2-2-2 HEX then refree whistled

Could be the changing in tactics helped me to score since i couldn't watch the real effect?

Would you suggest start the return leg. with the formation I could score with a goal or think of a more attacking tactic?
