Lefties can almost play any fundamental position, although it's best to keep them on the left side of the pitch rather than the right or center. As a result, the best positions for most left-handed players are left back, left halfback, and left flank. Right-handed players are usually assigned to right back, right halfback, and right flank.
Soccer is very much a team game, so even if you're only playing left-sided defense, you need someone else to help out. That's why it's important to have multiple players on the left side of the field; if one person gets pulled up by the coach for an extra attacker, another player can take his place.
Here are some other tips based on how they play left-handed: Left-footed players tend to be more aggressive than their right-footed counterparts. So if this description fits you, then you should feel comfortable playing left back or left halfback. Conversely, right-footed players should avoid those positions because they require more skill than strength. They would be better off with more defensive responsibilities or even in the middle where they can use their skills to make something out of nothing.
In conclusion, lefties can play any position on the field except goalkeeper and center back.
Modern-day left and right defenders (full backs) play an essential part in an offensive team's play since they generally supply width with overlapped runs and crosses into the box, with wide midfielders retaining their position to be able to step in for the full back if the team loses possession (player rotation).
Left defense and right defense are interchangeable terms. A left-footed player can play right defense or vice versa. However, most good players are naturally left-sided, so this isn't necessarily important unless you have very few options as to who can fill in at defense. Even then, you can usually find a way around it by using different positioning strategies. There are many different ways to defend as both a left and right defender.
Overall, a left defender tends to be more comfortable with the ball at his feet while a right defender is better without the ball. This is because most attacks start with the ball being moved towards the center of the field where there is more space; therefore, a left defender can use this advantage to win challenges and start attacking moves, while a right defender must rely on making sure his opponent makes a mistake.
They also tend to have different strengths. A left defender will often get forward early on in attacks, while a right defender stays back but still has the ability to block shots and clear the ball out of the box.
It doesn't make much of a difference, but a lefty has an edge when throwing from right field and a righty while throwing from left field. The ball tends to come back more quickly if you're facing the pitcher instead of into the wind. However, this advantage goes away if you stay in the game long enough for them to switch sides.
Overall, it's not worth switching positions just so you can hit from both sides of the plate. If you are a left-handed hitter, then there is no reason to play left field. You would be better off moving over to right field where you can hit for more power. If you are a right-handed hitter, then playing left field is your best option since most pitchers will let you hit behind the bag if you get a good pitch to hit.
However, if you can handle some speed on the base paths, then by all means try out left field. There are many shortstops who have success filling in left field because of their ability to catch fly balls.
Right and left defenders must work as a team rather than as individual playmakers. If a player is highly (for example) right-foot dominant, the right defense position might be used to hide it (but the left defender position could expose this). Conversely, if a player is highly (for for example) left-foot dominant, the left defense position might be used to hide it (but the right defender position could expose this).
In addition, right and left defenders can join in attacks by passing or shooting. For example, if the goalkeeper gets beat high up the field, the right back can pass to the center back who can then shoot at goal.
Finally, right and left defenders can help out their teammates by organizing defensive blocks. For example, if the opponent has the ball and is about to enter your area, you can call for a block on the right or left to prevent an entry pass.
