Hello champ,
While formation and tactics can be a relevant factor in winning a game, most people don't know that top eleven game engine has a way of turning the tide in deciding who wins a match.
I just beat a guy who was better than me in all areas. He won 1st leg 1:0 in his home and the return leg? He was bashed 5:0.
Same formation, same tactics and need I to say, same players.
I don't want to discredit the formations and counter formations posted on this forum BUT it doesn't work all the time.
Well, from my own experience.
Good luck mate in all remaining fixtures, you'll need it.
