Every Decision a Football Manager Makes During a Match

When fans talk about managerial decisions, they almost always mean substitutions. Who came on, when, and why. But substitutions are just the visible tip of a decision-making iceberg that runs for 90+ minutes every match.

Before kick-off

The starting lineup. Not just who plays, but where they play in relation to the opposition's shape. The tactical briefing tells each player their specific job — not "play well" but "when the ball goes to their left centre-back, press immediately."

The bench order. A top manager pre-plans two or three scenario-specific options: if we're losing at 65 minutes, this is the change. If we're winning and they press high, this is the change.

Set-piece instructions. Both attacking and defensive. Which routines to use in which zones, which players to block, which runner to free.

The first 15 minutes

The opening quarter-hour is information gathering. A smart manager reads what the opposition is actually doing — which might differ from pre-match analysis — and begins calibrating. Is our pressing trigger working? Are they exploiting our right channel? Is the No. 10 receiving too comfortably between the lines?

Continuous in-match decisions

Pressing adjustments. When to trigger the press, when to drop into a mid-block, when energy levels mean pressing isn't viable anymore.

Positional shifts. Telling a full-back to push higher or hold. Dropping the striker to press the pivot. Moving the No. 10 wider to create an overload. These micro-adjustments don't show up on any statistics sheet.

Managing yellow cards. A player on a yellow in a key position is one of the most complex ongoing decisions in football. Take them off and lose their quality. Leave them on and risk a red card. Every minute they stay on, the calculation shifts.

Reading the opponent's substitutions. When the opposition makes a change, a smart manager immediately asks: what problem are they trying to solve? How do we adjust?

The five substitutions

This is what most fans see — but the decision behind each substitution started forming 20 minutes earlier. The manager watching the game is already building the case: this player is gassed, this system needs fresh legs, this match situation calls for pace. The substitution is the end of the decision process, not the start.

Late-game management

Minutes 75-90 involve a completely different set of decisions. If winning: when to slow the tempo, who to protect the lead. If losing: how much to gamble, when to go with a second striker, whether the set-piece situation justifies abandoning the shape.

These decisions are made under the most pressure, with the fewest options remaining.

What this means for GAFFER

In GAFFER, you're not just making substitutions. You're making formation calls, flagging situations that need addressing, and tracking the moments when inaction becomes the wrong decision.

The five official substitutions are the decisions everyone sees. The rest of the game is the decisions everyone misses — until a manager gets one catastrophically wrong. The best Gaffers see them all.
