What happened: The tactical shift deployed Reus as an attacking option for the final half-hour of regulation. Calegari exited the pitch after securing a starting role in the contest.

Why it matters: The substitution mirrors a recent match where Reus entered in the 58th minute to provide a spark. Calegari continues to log minutes following his September return to the roster.

What to watch: The squad will lean on the fresh legs to dictate the tempo before the final whistle.
