Five matches. Five clean sheets. Barely a sniff of goal for the opposition.
That is the run Atlético Nacional have put together in the Copa Colombia, a stretch defined less by the scorelines they have produced and more by the ones they have prevented. In five games, the opposition has been held scoreless every single time. The underlying numbers back up what the eye test suggests: Nacional are conceding just 0.19 expected goals per game, a figure that points to a defence rarely allowing a clean look at goal, let alone a clean strike.
What the number actually means
An xG-conceded rate below 0.2 per match is the mark of a side that is not just surviving spells of pressure but suffocating them before they start. Across five matches, that works out to under one expected goal conceded in total for the entire run, a number that would be modest for a single match, let alone five.
Clean sheets can sometimes flatter a team that has ridden its luck or benefited from wasteful finishing at the other end. The xG data here suggests otherwise. Nacional are not just keeping the scoreboard blank, they are keeping the chances off the pitch altogether.
The run in numbers
- Clean sheets: 5 in 5 Copa Colombia matches
- Expected goals conceded: 0.19 per game
Whatever combination of shape, pressing triggers and personnel Nacional's staff have settled on, it is translating into one of the tidiest defensive stretches on record in the competition right now. For opposing attacks, the challenge is not just breaking down a well organised back line, it is finding a way to generate a shot worth taking in the first place.
Five clean sheets in a row is a statement. An xG-against figure of 0.19 per game is the explanation.
