The headline number is simple: 2-0.
Early in a season, teams are often judged less on fluency and more on whether they can turn decent spells into points. If the report is accurate, Derby did exactly that at Fratton Park.
If Szmodics and Salvesen were the scorers, Derby may have found value in different kinds of threat.
That matters over a long campaign. Teams that rely on one route to goal become easier to contain. Two different scorers in the same away win is a healthy sign.
For Portsmouth, the concern would be obvious if the report holds.
The next round now becomes important for both clubs. Derby will try to turn one reported breakthrough into a run, while Portsmouth need a response before an ordinary setback starts to feel like an early trend.
