Perhaps your able to tell me what im doing wrong to lose
There are 2 problems here:
1. Lack of squad talent or the lack of the right sort of players. I am guessing here, but your best player is all offense and not much defense. From your last few games, your team got pawned big time on outside defense. As demonstrated by your game against Team Akuma, your team can shoot from outside and do almost nothing else.
2. Wrong tactics. Using ur latest game, playing a 2-3 zone against a team that is stronger on the outside is inviting them to shoot and needless to say you got pawned.
Additional reasons could be a lack of depth and not having high enough enthusiasm.
At 5-10 and sitting in 5th, your best bet is to try finish the season in 5th place. Save up for a decent player inside player next season as you are seriously getting pawned in the inside.
