Providing defensive tips for set pieces

I'm focusing on answering the user's question about defensive techniques for soccer set pieces, in Chinese. I'll create concise, actionable tips, like organization, marking strategies (man-to-man, zonal, mixed), starting positions, and body orientation. I also need to cover offside traps, wall setups, goalkeeper roles, and specifics for defending corners. I should aim for a structured list of about 4 to 6 bullets, considering the formatting constraints. Diagrams might be tricky, but I'll think about simple ASCII representations if necessary.Structuring defensive techniques

I’m planning to create multiple sections for tips on defending set pieces: Overall principles, Corners, Wide free kicks, Central free kicks, Throw-ins, Common mistakes, and Training drills. Each section will have about 4 to 6 concise bullets for clarity.

In general principles, I’ll cover role assignments, starting positions, line management, defender movements, and communication. For corners, I’ll focus on zonal protection, man-marking best headers, and positioning for posts. It's a lot, but it should be super helpful!Examining defensive strategies

I’m identifying some current trends for set pieces, like not having a player on the far post, although youth or amateur teams might do that if they’re underdogs. For corners, having an edge-of-box player is key, as is using a counter threat with a couple of players high. I should also emphasize safety-first clears and offside lines for wide free kicks. For central free kicks, proper wall setup is essential, including covering posts and being aware of short passes.Outlining throw-in defense strategies

I need to cover throw-in defense, focusing on matching feet to the touchline, denying turns, and marking long throw threats. It's essential to have one player in front of a long throw to block, and the goalkeeper should prepare for near-post flicks while staying positioned for second balls.

Common mistakes include ball-watching, losing runners, and mis-timing line drops. For training, I'll suggest rehearsing assignments, using call sheets, video reviews, and specific drills like 6v6 corners. A simple template for corner defense could include combinations of zonal and man-marking strategies. Let's finalize that!
