Your players remember about half of what you say

Fewer ideas, not fewer occasions

The usual advice — give less feedback — has weaker support than people assume. Meta-analyses of reduced feedback frequency find no clear benefit. What did measure up in the study above was that when the number of ideas in a message went down, the information became more coherent and players retained more of it.

So keep the frequency and cut the content. Decide three messages for the whole session, write them down before you go out, and repeat each of them several times using the same words. One message per intervention, one focus per clip. Saying the same thing three times feels repetitive to you and is about right for a fourteen-year-old.

Your feedback is probably more prescriptive than you think

Observational studies of youth coaches paint an uncomfortable picture. In Spanish U10 teams, 60 per cent of all feedback was prescriptive — do it like this — and just over half was negative in tone. Coaches with a sports science education used more corrective and specific feedback and fewer plain reprimands, which shows this is a skill that can be learned rather than a personality.

Questions do get asked — around 70 per session among professional youth coaches. The problem is that roughly half are checking questions rather than learning questions. The difference decides whether the player thinks or simply answers.

• Checking question: "Who was your nearest teammate there?" It has a right answer and you already know it.
• Learning question: "What were three ways to solve that situation, and why did you choose the one you did?"
• Count your own questions once a season. Film a session, or ask a colleague to tally them. It is the cheapest self-assessment available to you.

Stop stopping the game

Observational data shows that just over 16 per cent of session time goes on the coach freezing play and gathering everyone. That is a sixth of the training with nobody touching the ball, paid for in the currency that matters most for learning football: contacts with the ball in game-like situations.

Coach on the move instead. Walk alongside the player at the next natural break and give them one sentence. If you need to change the behaviour of the whole group, a constraint is nearly always more effective than a talk: force the behaviour through the conditions of the game instead of explaining it.

Clips: ten to twenty seconds, one focus

Video of yourself works — a systematic review finds a moderate to large effect on performance. But the effect depends on the dose. Occasional sessions far apart leave nothing behind; treat video as an ongoing dose, not as an event.

The most practical finding is that clips work best before the activity, not only after it. In one study 24 players around the age of 14 watched four minutes of video during a five-minute rest between small-sided games, and their playing behaviour changed measurably in the block that followed. So show the moment you intend to train, then go straight out and train it.

• Ten to twenty seconds per clip, one focus, at most two plays.
• Put one line of text on the clip saying what the player should look for.
• Let the player choose when to watch. Self-controlled video feedback produces higher engagement and deeper understanding than when the coach picks the moment.
• Ask the player to describe the clip before you do: what do you see, what were the options, what will you choose next time?
• Never show a named player’s mistake on the big screen to the whole team without speaking to that player first.

Praise the choice, not the player

Classic experiments by Mueller and Dweck showed that children praised for their ability after a success went on to choose easier tasks, while those praised for effort chose harder ones. Praise for talent makes you protect your reputation. Praise for process makes you willing to fail, which is the entire mechanism behind getting better.

The difference is small in wording and large in effect: "good that you checked your shoulder before receiving" instead of "you are such a talent". And criticism about a situation can be trained away, while criticism about the person sticks.

The parents hear you too

Hold a parents’ meeting before the season and spend fifteen minutes purely on match conduct. Hand over three requests in writing, so they survive into the season: cheer for the team collectively, no instructions to individual players, no criticism of the referee.

Have a ready-made sentence for when you need to intervene in the moment, so you do not have to invent one while angry. The Swedish FA’s suggestion works: "I can hear something is happening here — I want to understand and help." And keep a parent’s worry separate from a parent’s behaviour. The substantive issue — playing time, position, selection — gets its own private meeting. The touchline is a different matter and is not up for negotiation.

Common follow-up questions

How often should I give feedback during a session?

As often as it is needed. Frequency is not the problem — the amount in each message is. A better measure than the number of interventions is how many ideas you packed into the last thing you said. If it was more than one, say it again.

Should I show clips to the whole team or individually?

Team moments as a group, individual mistakes individually. That is the only line you need. A good group clip shows a moment you are about to train; a player singled out in front of everyone learns nothing except caution.

Does video feedback work on 13-year-olds?

Yes, and the most convincing results come from exactly that age group. The condition is brevity and regularity. Four minutes of clips before a small-sided game made a measurable difference in the study above — a half-hour review once a month does not.
