what kind of team to you want to build? what formation are you going to generally play out of? Before you build a team, think about how you want to play the game.
I generally play out of the 4-4-2 and all the variations of it. This year I switched to 4-3-3. I originally wanted to try a false 9 approach but honestly it is not really my style. I build up between my midfielders and wingers then feed my forward ground passes for goals. majority of my goals are inside 10 meters from the goal.
The way I am building my team.
wingers are key to my attack, I look for dribbling, short pass, vision, and finishing as my primary skills. I only look at physical skills to make decisions on players when technical skills are equal or close to it. Although my focus is to score with my forward, these guys still need to be able to score, so finishing is very important.
CF / ST position just needs to have ball control, short passing, finishing, weak foot and attack position skills. I rarely attack from crosses, so my forward just gets fed all game long. If I can't get a pass directly to him from the wing, then I take hard shots at the edge of the box and try to get a deflecting from the keeper to him.
central midfielders just need stamina, short and long passing, free kick, curve, etc. These guys setup the wingers, who then setup the forward. Because I am looking for specific abilities from the wings and forwards, these guys need to be able to fill in with the other team skills free kicks, penalties, corners, etc. although my fullbacks generally have crossing and curve skills for corners.
defenders, just need defensive skills, jumping, and heading skills for set pieces.
