I've been trying to find a good attacking tactic and defensive one. And finally i manage to combine Arsenal, Chelsea, and united style of play. Arsenal and united are good at attacking, while i choose chelsea for defense. Been trying this tactic with arsenal chelski, united, and currently plymouth. So far so good for my plymouth side, even i manage to beat liverpool 4-2 and arsenal 2-1. Well, anyway about the tactic:
Arsenal_United Attacking
This tactic is mainly focus on pin-point passes and through balls. 3 player who are the most important part for this tactic, and they are:

1. Striker
The blue one, this is henry's job. He will receive a through pass from the midfielder, and then take the ball direct to the goal until he only face the gk.
I recommend you to put a striker with high creativity, dribbling, pace, and composure so its easier for him to score as he will face the gk in one on one.
And the second striker job is to take the rebound and score the goal.

2. Midfield Playmaker
The red one, another creative player. Carrick/fabregas does it. This is the source of your attack. Dictates the game, and often do through ball passes.
The playmaker needs a high creativity, passing ability, and technical.
3. Wingers
Two wingers needed for this tactic. They will dribble pass the opponent and give a through ball to the strikers. They won't do too much crossing. The wingers need to have a high dribbling, pace, technique, and passing.
Note: You can use this tactic either with counter attack or not (I usually use)
Arsenal_Chelsea Defensive
Lets say you already have 3 points in your hand and you want to maintain it. This tactic plays more defensively and often do the time wasting.
The most important part of this tactic:
1. 3 Midfielder
In chelsea, they are ballack, lampard and essien. The center mid is a playmaker. In this tactic, the playmaker will oftenly do a longshots, which will help for wasting time (in my opinion).
The two other midfielder will support both attack and defense, so they must have good work rate and stamina.
2. Defensive Midfielder
Very defensive minded with full closing down. He will prevent the opposition attacker to get to defensive line. Stamina, tackling, and work rate are highly needed for him.
So far, these tactic are good for me. Gonna post some screenies soon. Anyway, you have to REMEMBER that these tactic are not miracle or cheat tactic or something like that.
I can't guarantee you will have 38 winning streak in league. If you wish, please leave some feedback or suggestion. Thanks.
