Of course he can!
We only need the proper "structure", to help ETH with a few things:
1. Someone to buy the right players.
2. Someone to decide which 11 players he will use in each game, because ETH cannot really understand who the best players are. (For example, he believes that Antony is unstoppable.)
3. Someone to decide which system we'll use, because ETH can't see the holes in the middle.
4. Someone to help with the in-game management and subs.
5. Someone to help with man-management, because ETH gets into unnecessary fights with players.
6. Someone to take over the training, because ETH's training probably caused too many injuries.
If "the structure" provides the proper help, then yes, ETH will win it all!
