This achievement requires you to beat the bronze, silver and gold challenges on one skill game. The easiest skill game in my opinion is the dribbling one. I prefer to use Ronaldo over Messi but that is just me. To change the player you use just go to skill games and then select team/player. Select the team of your choice and player of your choice. One tip is to hold when going round the cones as it keeps the ball close to you and the player moves a lot slower. This prevents you from hitting the cones and taking the ball out of bounds. These again should not be too hard.
