there were at least 60+ comments on what SAF should do/don't.
I think SAF maybe will bring in one or max two to strengthen but
not to disturb balance.
It seems the current crop of players are enjoying playing together.
I do rem once when an opposing player mentioned MUFC players
cursing and shouting at each other, but now, with newborn
confidence, they know that even with a goal down (benfica game),
they can get back into the game.
So SAF will need to thread carefully.
