Summary: Get the most out of drills by working hard and using them creatively to improve and maintain your skills.
A good soccer player needs several skills like moves, shooting, and passing. To be successful on the soccer field, the player needs to master all the skills. Once the player masters the skills, he or she needs to maintain these skills indefinitely. The best way to maintain skills is consistently do soccer drills.
Most soccer teams run through drills in practices. Unfortunately, a lot of players see drills as a chore that they do only to get through the initial stages of practice. Instead, they should be putting as much concentration and work in those drills. There are two advantages to this approach. First, if you work hard at drills, that work ethic will carry over to actual games. Second, if you master the skills, you will get an edge over other players.
Another extremely useful way to approach drills is to treat them as real world games. You will improve, but by changing your approach to the drills, you can take your game to the next level. Take a simple example of shooting practice at the net. Once you can easily kick the ball in with power, start thinking about ways that you can approach it in a match environment. Take shots assuming there are some defenders and a goalie. This way, when you do end up in that situation, you will know what to do and how to do it.
There is no specific drill that you need to do, just how you approach it.
