Some good attributes to look for in players are:
- Work rate, Decisions
- Teamwork, Determination
- Passing, Creativity
- First Touch, Anticipation
Obviously you won't be able to find all these attributes in a player but the more you can find the better.
Some good preferred moves to look for are:
- Get further forward(for your AP and IFs)
- Cut Inside( for IFs)
- Play a Simple Passing Game
- Play one-twos(For attacking players)
Some attributes that are bad for this style are:
- Dwells on the ball
- Tries long range passes
- Shoots from Range
- Looks for killer balls often
- Any others you think would lead your team to give the ball away unnecessarily
The training I would use is tactics on very high during pre season with teamwork as pre match training. Then I would leave the training on tactics and very high for the first season as it may take a few months for the team to be really familiar with the tactic. During the season I alternate between attacking movement and defensive positioning depending on the opposition. After the first season you may want to alternate between training fitness to help with pressing or team cohesion to help with there teamwork.
One last thing is don't do opposition instructions as you want teams to react to you not for you to react to them.
