In brief

AI summary

Community-favored 26/27 defensive setups use five or six defenders, low style, deep defending, and counter-attacks or shoot-on-sight tactics.
Defensive choices should match the opponent: protect the wings against Wing play, maintain pressure against Shoot on sight, and consider central midfield overloads against Passing game.
Use zonal marking, keep the offside trap off by default, reduce tackling against strict referees, and note that these community recommendations remain untested.

For an OSM defensive tactic in 26/27, the community's leading setups are built on a back five or six and a low style: 5-4-1B with Shoot on sight, and 5-3-2 or 5-3-1-1 with Counter-attack. But the opponent's game plan changes how you should defend; the same "bus" does not work against everyone.

The setups come from OSM Helper's site tactics, and the opponent-specific warnings from OSM Next Level's guides, a community tool. We have not tested them.

What the defensive settings mean in-game

OSM pre-match tactics screen: Passing game plan, Normal tackling and line tactics

Setting	Defensive option	Effect
Style	0–19 Park the bus, 20–39 Defensive	More players stay behind the ball
Pressing	0–19 Don't press, 20–39 Sit deep	The team stays compact and waits in its own half
Defenders	Defend deep	The back line stays deep
Midfielders	Protect the defence	The midfield drops in front of the defence
Forwards	Drop deep	The forwards help defend too
Game plan	Counter-attack	Sit deep and break quickly

The in-game slider band names come from OSM Helper's list of in-game labels. According to OSM Next Level's guide, style sets how attacking the team is, pressing what happens without the ball, and tempo how fast you play.

The community's defensive setups

OSM line-up screen with a 4-3-3 starting eleven and tactics and specialists shortcuts

Formation	Game plan	F / M / D	Pressing/Style/Tempo	Flagged for
5-4-1B	Shoot on sight	Support midfield / Protect the defence / Defend deep	39/29/59	All situations
5-3-2	Counter-attack	Attack only / Protect the defence / Defend deep	30/25/60	Stronger opponents (home and away)
5-3-1-1	Counter-attack	Attack only / Protect the defence / Defend deep	10/15/80	Stronger opponents (home and away)
5-2-3A	Counter-attack	Attack only / Protect the defence / Defend deep	70/30/70	Stronger at home; even and stronger away
6-3-1A	Counter-attack	Attack only / Stay in position / Defend deep	80/45/50	Even and stronger opponents away

What they share: defenders on Defend deep, the offside trap off and style at 45 or lower. Tempo is 59 or higher in four of the five; a defensive side wants to break quickly once it wins the ball. The 5-3-1-1 at Pressing 10 and Tempo 80 is the extreme version: no pressing at all, then one-touch football once the ball is won.

Defending by opponent: one bus does not fit all

Against Wing play: According to OSM Next Level, the biggest weakness of back fives is sustained wing play, which stretches the line. Pick wide defenders with strong defence ratings and keep your midfield on Protect the defence.
Against Shoot on sight: According to the same source, retreating against these sides hands them shooting space in front of the box. Here, defending means taking the ball off them; do not switch pressing off entirely.
Against Long ball or Counter-attack: According to OSM Helper's guide, the offside trap can work against these plans. OSM Next Level rarely uses it, though; if your line cannot step up together, do not take the risk.
Against Passing game: Since Passing game builds through the middle, back fives that crowd the centre with three central midfielders (5-3-2, 5-3-1-1) look the more logical choice.

Marking, offside and tackling

Marking: Under OSM Next Level's rule, use zonal marking if your defenders outnumber the opponent's forwards by at least one, and man marking if not. With five or six defenders, zonal marking is enough against almost any opponent.

Offside trap: Off by default. Setting a trap with a deep-lying defence contradicts the setup anyway.

Tackling: According to OSM Helper, referees get stricter from green to red, and you should lower your tackling as they do. Defending means lots of duels, and one red card can wreck the whole plan.

Other tools that strengthen your defence

According to OSM Helper's guide, secret training stops opponents spying on you and adds 2.5% performance, while a training camp gives a 25% boost in the next match. We could not confirm these figures in an official source. Developing your defenders through training is also a lasting fix.

What changed since our older guide

Our 2022 defensive tactic guide centred on a single setup. The 26/27 version adds several community setups and explains what to change depending on the opponent's game plan. The tactics screen is the same, and OSM's official help page still recommends testing a tactic in a friendly.

Frequently Asked Questions

What is the best defensive tactic in OSM?

There is no single answer. Community setups revolve around a back five or six, a low style and Counter-attack; which one works depends on the opponent's game plan.
