The recent announcement that Adam Gemili is stepping into a speed coaching role within the academy at Chelsea FC should be seen as more than a progressive hire.
But it’s also worth saying this clearly: it isn’t new. It isn’t novel. It’s common sense.
I remember discussing this exact point with my former gaffer some time ago. His response was simple, we used to employ an athletics coach in the Junior Academy for precisely these reasons.
In other words, this is not innovation. It’s a return to something the game has always known but hasn’t consistently applied.
Gemili, of course, arrives with a decorated career at the very highest level of sprinting. An Olympian and one of Britain’s fastest ever athletes, he won European Championship gold as part of the 4x100m relay team and competed consistently on the global stage across Olympic and World Championship cycles. Known for his explosive starts and powerful acceleration phase, his profile is built not just on raw speedbut on a deep, technical understanding of how speed is generated.
That matters.
Because what he brings into the academy environment is not theory. It is applied, elite-level knowledge of acceleration mechanics.
And his central point is both simple and profound:
Young players don’t fully understand how to accelerate—how to put force into the ground to generate speed.
It’s a recognition of something the game has been slow to fully grasp:
Speed is not just a physical attribute. It is a technical skill.
And, crucially, it is a skill that is often misunderstood, misidentified, and under-coached in football development.
The Misconception: “He Can’t Move”
One of the most common phrases heard in talent identification environments is:
“He can’t move.”
But scratch beneath the surface, and what does that actually mean?
More often than not:
- The player is quick over short distances
- They can separate from opponents
- They are effective in duels
Yet they are dismissed because:
- Their running style looks awkward
- It’s not aesthetically “clean”
- It doesn’t resemble textbook sprinting mechanics
This is where the danger lies.
Efficiency vs Aesthetics
There is a critical distinction between:
- How a player looks when they run
- How effectively they move
Some players:
- Generate high force despite unconventional mechanics
- Compensate in ways that still produce acceleration
- Win the actions that matter (first 5–10 yards)
To the untrained eye, that can be misread as a limitation when considering potential.
In reality, it may be:
- A coaching opportunity, not a ceiling
- A technical inefficiency, not a lack of athleticism
Where Gemili’s Role Becomes Significant
This is precisely where Gemili’s intervention is so important.
His focus on:
- Force application into the ground
- Acceleration mechanics over 5–10 yards
- Helping young players understand how speed is generated
This focus directly addresses the gap between perception and performance.
The aim is not to “tidy up” players for aesthetic reasons.
It is to:
- Improve efficiency
- Reduce wasted movement
- Enhance repeatable acceleration under game conditions
In other words:
Turn “effective but inefficient movers” into consistently dominant athletes
Why This Matters in the Modern Game
The modern game is defined by moments, not distances.
- Pressing actions
- Transitional bursts
- 1v1 duels
- Runs in behind
These are decided in:
The first 5–10 yards
Players like Kylian Mbappé or Erling Haaland don’t just have pace they have elite acceleration mechanics.
They win:
- The first step
- The first contact
- The first advantage
And that is often the difference at the highest level.
The Development Window: Why Early Matters
This is where the data becomes particularly compelling.
- ~60% of players who go on to make a Premier League debut enter academies at U9 (signing age)
- ~80% enter during the Foundation Phase (U9–U12)
That tells us something important:
The majority of future professionals are already in the system when movement patterns are being formed.
And here’s the key implication:
- Sprint habits, good or bad, are embedded early
- By the time players reach the Professional Development Phase:
- Mechanics are ingrained
- Inefficiencies are harder to correct
The Missed Opportunity in Early Development
Despite this, speed is still often:
- Treated as natural
- Assessed visually rather than technically
- Left to develop organically through games
But if speed is a skill, then:
It shouldn’t it be coached with the same intent as passing, receiving, or decision-making?
Particularly in the Pre-Academy and Foundation Phases.
At U6–U8, we’re not talking about:
- Sprint sessions
- Repeated efforts
- Conditioning blocks
We’re talking about:
Movement education, not performance training
This aligns perfectly with what athletes in sports like athletics are exposed to early—fundamental movement patterns before anything formal.
Why Pre-Academy Is Actually the Ideal Window
From a development perspective:
- Neural plasticity is at its highest
- Movement patterns are not yet ingrained
- Players are naturally exploratory in how they move
This is when you can:
- Introduce basic acceleration shapes
- Develop coordination and rhythm
- Build foundations without resistance or overthinking
By contrast, if you wait until the youth development phase:
- Habits are already formed
- Inefficiencies are harder to change
- Players have already been selected based on flawed interpretations of movement
Reframing Talent Identification
This brings us back to the original point.
When a scout says:
“He can’t move”
We should be asking:
- Can he accelerate effectively over 5–10 yards?
- Does he win actions in game-relevant moments?
- Is the issue output, or just how it looks?
Because if it’s the latter:
We may be rejecting players not because they lack speed but because they lack polish.
And polish can be coached.
The Bigger Shift
Gemili’s appointment is part of a wider evolution.
But perhaps more accurately it should be seen as a reaffirmation of best practice.
- Cross-sport expertise entering football
- Greater focus on movement literacy
- Recognition that physical development is technical development
This is not about turning footballers into sprinters.
It’s about ensuring that:
Every player has the tools to express their speed efficiently, repeatedly, and under pressure
Final Thought
If:
- The majority of elite players are identified and developed before U12
- Speed is decisive in the modern game
- And sprint mechanics are coachable
Then the conclusion is hard to avoid:
Acceleration training isn’t an add-on. It’s a foundational pillar of player development.
And perhaps most importantly:
The next time we hear “he can’t move”, we should pause because we might be looking at a player who can, just not in a way we’ve been taught to recognise.
