Let’s be honest for a second—watching Chelsea this season has felt like riding a roller coaster that occasionally forgets to check the safety bar. One minute we’re dismantling a lower-table side with the kind of fluid football that makes you believe in the project, and the next we’re watching a midfield get overrun by a team that’s spent half their budget on a new training ground. The talent is there—€1.09 billion worth of it, the youngest squad in the Premier League—but talent alone doesn’t win you games. So what keeps tripping us up? Here’s the breakdown of the tactical mistakes we need to leave behind in 2026.
The High Line That’s More of a High Risk
You’ve seen it. We push up, the full-backs are practically in the opposition’s half, and then one long ball over the top leaves our center-backs sprinting backward like they’ve just remembered they left the oven on. It’s a problem that’s haunted us under both Maresca and now under Calum Macfarland’s interim spell. The idea is sound—compress the pitch, win the ball high, create chaos. But the execution? It’s been shaky at best.
The issue starts with the defensive line’s lack of cohesion. Levi Colwill has the pace to recover, but when he’s dragged wide to cover for an advancing Reece James, the middle becomes a no-man’s land. And with a goalkeeper like Robert Sanchez, who’s comfortable with the ball at his feet but not always decisive sweeping up behind, you’re essentially inviting opponents to test your backline’s sprint speed. It’s a mistake that cost us against Tottenham earlier this season—a game we broke down in detail here—and it keeps resurfacing.
What to do instead: The fix isn’t to drop deeper and invite pressure—that’s not the Chelsea way. But the midfield needs to offer better protection. Moises Caicedo and Enzo Fernandez have the legs to screen the defense, but they’ve been caught between pressing and covering. A simple adjustment: have one midfielder sit slightly deeper when the full-backs push on. It’s not sexy, but it stops those counter-attacks before they start.
Midfield Overloads That Leave Us Exposed
Speaking of the midfield, let’s talk about the numbers game. Chelsea’s system often funnels play through the center—Cole Palmer drifts inside, Enzo looks for pockets, and Caicedo tries to break lines. It’s pretty to watch when it works. But when it doesn’t, we’re left with a single pivot trying to cover the entire width of the pitch.
The problem is particularly acute against teams that pack the midfield with three or four bodies. Our 4-2-3-1 can become a 4-1-4-1 in possession, and if the opposition wins the ball, they’ve got a free run at that lone defensive midfielder. Caicedo has been exceptional at covering ground, but even he can’t be everywhere. And if the full-backs are caught high—which they often are—the result is a 3-on-2 or 4-on-3 situation that no center-back pairing can handle.
The adjustment: It’s about discipline. One of the attacking midfielders—and I’m looking at you, Cole Palmer, even though you’re our best player—needs to track back more consistently. Palmer’s 9 goals this season are vital, but his defensive contribution has been minimal. That’s fine if the system compensates, but right now, it doesn’t. A simple rule: when the opposition transitions, one of the front four must drop into the midfield line. It’s a small change that could save us three or four goals a season.
The Set-Piece Vulnerability
This one drives me mad. We’ve got the height—Colwill, Chalobah, even Delap when he’s on—but we defend set-pieces like we’ve never seen a corner before. It’s not just about conceding goals; it’s about the psychological blow. You dominate a game for 70 minutes, then a floated ball into the box undoes all that work.
The root cause is a mix of poor zonal marking and a lack of communication. Players get attracted to the ball, leaving runners free at the back post. And when the goalkeeper doesn’t command his area—Sanchez has been hesitant on crosses—it’s a recipe for disaster. We’ve seen it against Manchester City in the FA Cup final buildup, and it’s a pattern that needs breaking.
The fix: It’s not about overhauling the system. It’s about drilling the basics. Assign specific players to specific zones, and make sure the goalkeeper is vocal. If you’re going to use zonal marking, you need everyone to trust the system. One player ball-watching, and it falls apart. This is something Macfarland can fix in training without changing the entire tactical setup.
Over-Reliance on Individual Brilliance
Let’s face it—Cole Palmer has been our savior more times than we’d like to admit. Nine goals, one assist, and countless moments where he’s bailed us out. But a team that relies on one player to create magic is a team that’s one injury away from disaster. When Palmer is double-marked or has an off day, our attacking output drops off a cliff.
The same goes for our wingers. Pedro Neto has shown flashes, Garnacho has the raw talent, and Estevao is still settling in, but they’re not consistently creating chances. We’ve become too predictable—give the ball to Palmer, hope he does something. Defenses in the Premier League are too good for that to work week in, week out.
The solution: Spread the creative load. Enzo Fernandez has 8 goals this season, which shows he can contribute, but he needs to be more involved in the final third. Liam Delap and Joao Pedro need to be given clearer instructions on how to pull defenders out of position. It’s about creating patterns that don’t rely on one player. If you can make the opposition defend the whole pitch, you’re harder to stop.
The Transition Problem
This is the big one. Chelsea’s squad is built for speed—Garnacho, Neto, Delap, Estevao—but we’re not using it effectively in transition. Too often, we win the ball back and then slow the play down, allowing the opposition to regroup. It’s like having a sports car and driving it in first gear.
The issue is partly tactical and partly psychological. Players are hesitant to commit to a counter-attack because they’re worried about losing the ball and being exposed. But with the pace we have, we should be punishing teams on the break. When we do commit—like in the Conference League run last season—it’s devastating. But in the Premier League, we’ve been too cautious.
The change: Trust the speed. When Caicedo or Enzo win the ball, the forwards need to be sprinting forward immediately. No sideways passes, no waiting for the full-backs to overlap. Just get the ball into space and let the attackers run. It’s a simple instruction, but it requires bravery. If you lose the ball, you’ve got the recovery pace to get back—use it.
When to Call in the Experts
Some of these issues are fixable on the training ground. Others require a deeper look at the squad’s structure. If you’re a fan trying to understand why we keep conceding from set-pieces, you can watch the replays and spot the patterns yourself. But if you’re looking for a full tactical overhaul—like changing the defensive line or the midfield shape—that’s a job for the coaching staff. Macfarland has shown he’s willing to make adjustments, but he’s working with a squad that’s been through three managers this season. Consistency takes time.
For the rest of us, the key is to stop repeating the same mistakes. We know the high line is risky. We know the midfield can be overrun. We know we rely too much on Palmer. The question is whether the team can learn from it before the next big game—like that FA Cup final against Manchester City. If they don’t, we’ll be having this same conversation next season.
