Barcelona beat BATE Borisov 4-0 while Viktoria Plzen scored two late goals to claim a 2-2 draw against AC Milan in the Champions League.
A youthful Barca outfit were far too good for their Belarusian opponents at the Nou Camp as the reigning La Liga champions finished Group H unbeaten.
With their qualification as group winners already confirmed, Pep Guardiola chose to select a young side with an average of just 23.
But despite that, Barcelona cruised to victory and they played in a similar way to their more experienced team-mates, highlighting just what an outstanding football philosophy the club possesses.
Guardiola's side knocked the ball around with ease and after Rafinha and Sergi Roberto went close, the latter broke the deadlock.
The sweeping move involved Thiago and Pedro and Roberto applied a cool finish to give Barcelona the lead on 35 minutes.
That advantage was doubled with half an hour to play, when Montoya opened his account and three minutes later Pedro produced a sensational finish with his heel at the near post to make it 3-0.
Pedro got his second for the night from the penalty spot with 10 minutes remaining as Barca finished the group stage with 16 points from six matches.
The other Group H match saw Viktoria Plzen produce a terrific comeback to win themselves a spot in the Europa League.
Alexandre Pato and Robinho scored just after half-time for Milan and with five minutes to go it seemed like they would cruise to a comfortable win.
But Plzen had other ideas, with David Bystron and Michal Duris both scoring late on as they secured a famous draw in Prague.
The point will give them inspiration ahead of the Europa League, which they will enter as a result of finishing third in the group.
