Let’s be honest—watching Chelsea defend a corner this season has felt like playing Russian roulette with a fully loaded chamber. You know that jolt of anxiety when the referee points to the corner flag? Yeah, me too. For a squad packed with significant talent and high market value, the Blues have developed a habit of making set-piece defending look like an afterthought. But here’s the thing: it doesn’t have to be this way. Let’s break down what’s actually going wrong and, more importantly, how Calum Macfarland and his coaching staff can fix it.
The Core Problem: A Young Squad Lacking Structural Discipline
Chelsea’s squad is among the youngest in the Premier League this season. That’s exciting for the future, but it’s a nightmare for set-piece organisation. When you’re defending a corner, you need split-second decision-making, clear communication, and a ruthless physical presence. Too often, we’re seeing players ball-watching instead of tracking runners, and static zonal marking that leaves gaps big enough to drive a truck through.
Take the recent run of games under Macfarland. Opponents have consistently targeted Chelsea’s near-post area during corners. Why? Because the Blues’ defensive line tends to drop too deep, leaving the near post exposed. The result? Easy flick-ons and tap-ins that could have been prevented with better positioning.
| Weakness | What It Looks Like | Impact on Matches |
|---|---|---|
| Zonal marking confusion | Players freeze in zones instead of attacking the ball | Opponents win headers unchallenged |
| Poor communication | No clear caller; defenders collide | Goals conceded from routine corners |
| Weak first contact | Failure to clear the near-post area | Second-phase chances created |
| Lack of physical presence | Young players bullied by experienced headers | Set-piece specialists thrive |
Step-by-Step Solutions: What Macfarland Should Change
The good news? Most of these issues are fixable with targeted training and tactical tweaks. Here’s a practical roadmap.
1. Assign Clear Roles and a Single Caller
Right now, Chelsea’s set-piece defence lacks a clear leader. The solution is simple: designate one player—ideally a vocal defender like Levi Colwill or a midfielder like Moises Caicedo—as the primary caller. That player decides whether to step up, drop, or mark zonally. No debates. No hesitation.
2. Drill the Near-Post Defence Religiously
Macfarland should run drills where the entire backline practices defending the near-post area under pressure. Use cones to mark the danger zone (from the goal line to the six-yard box, near post to the penalty spot). Every player must know their responsibility: the first man attacks the ball, the second covers the flick-on, and the goalkeeper commands the six-yard box.
3. Introduce a Hybrid System
Pure zonal marking isn’t working for this young squad. A hybrid approach—where key threats are man-marked while others cover zones—could be the sweet spot. For example, assign Enzo Fernandez or Cole Palmer to track specific runners, while the central defenders hold their zones. This gives structure without sacrificing flexibility.
| Solution | Implementation | Expected Outcome |
|---|---|---|
| Assign a caller | Choose one vocal leader (e.g., Colwill) | Clearer communication |
| Near-post drills | 20-minute daily sessions | Reduced concession rate |
| Hybrid marking | Man-mark threats; zone the rest | Balanced coverage |
| Use height effectively | Target Liam Delap on offensive corners | Turn weakness into weapon |
When the Problem Requires a Specialist
Let’s be real: some issues go beyond tactical tweaks. If Chelsea continues to concede from set pieces despite drilling these basics, it’s time to bring in a dedicated set-piece coach. Many top Premier League sides now employ specialists who analyse every delivery, every block, every run. The Blues’ current setup, with Macfarland juggling interim management and tactical duties, simply can’t give set pieces the attention they deserve.
Also, consider the personnel. If Robert Sanchez struggles to command his box, that’s a goalkeeper-coach issue. If the central defenders consistently lose aerial duels, that’s a recruitment problem. For the 2025-26 season, Todd Boehly and the recruitment team might need to prioritise a commanding centre-back or a goalkeeper who dominates the six-yard box.
The Bigger Picture: How Set Pieces Fit Chelsea’s Season
This isn’t just about corners. Chelsea’s set-piece defending is a symptom of a broader issue: a squad that’s still learning how to win ugly. In the Premier League, matches are often decided by dead-ball situations. For example, tight games can come down to who can defend a corner or score from a free kick.
Macfarland has a golden opportunity to address this now, during the run-in. If Chelsea can tighten up at the back, they become a much more dangerous side.

Your Turn: What Would You Change?
Look, I’m not saying Chelsea needs to become a defensive juggernaut overnight. But the current approach is costing points—and that’s frustrating when you see the attacking talent on display. The solutions are there: better organisation, clear roles, and maybe a specialist coach. It’s up to Macfarland and the squad to execute.
