Three league points and goal difference hinge on the Alianza Lima–Huancayo result on July 19.

The outcome affects Alianza's title push or Huancayo's placement and can change qualification for continental tournaments or survival calculations late in the season.

Alianza Lima and CS Huancayo supply the lineups, coaches, and club staffs whose choices decide the result.

Key figures include each side's starting forwards, the managers' tactical calls, and the referee managing game flow and discipline.

Recent form, injuries, and squad rotation will shift win probabilities for both clubs.

Weather, home advantage at Alianza's stadium, and set-piece effectiveness also matter, as does any fatigue from midweek fixtures or continental travel.

Kickoff is July 19; watch the starting XIs announced about an hour before kickoff.

Track substitutions, injury updates in the first 30 minutes, and disciplinary decisions that can change momentum. Also note attendance and pitch condition reports.
