Arda Turan grabbed a hattrick and Lionel Messi his 10th Champions League goal of the season as a much-changed Barcelona still cruised past Borussia Moenchengladbach 4-0 on Tuesday.
Barca had already booked their place in the last 16 as Group C winners, but were looking for a morale boosting win after three successive draws, including the concession of a last minute equaliser to Real Madrid in a 1-1 draw on Saturday.
Messi continued to cut the gap on Cristiano Ronaldo as the Champions League's all-time top goalscorer when he slotted home the opener after just 16 minutes.
Turan then struck his first Barca hattrick in a 17-minute second-half spell as the hosts took out their frustration on a dispirited Monchengladbach.
Whilst Barca can look forward to the last 16 for a 13th straight season, third place in the group behind Manchester City ensures Moenchengladbach drop into the Europa League.
Barca boss Luis Enrique retained only Messi, Andre Gomes and Javier Mascherano from the side that started El Clasico on Saturday.
And Messi's insatiable appetite for goal was rewarded when he exchanged passes with Turan to sweep home his 93rd in the Champions League, now just three adrift of Ronaldo in the race to be the first man to a 100.
The five-time World Player of the Year was the persistent threat throughout the first 45 minutes, but Barca captain Andres Iniesta also impressed on his first start for six weeks after a knee injury.
Only Moenchengladbach 'keeper Yann Sommer prevented Messi from adding to his tally before half-time.
However, it was Turan who took centre stage after the break as he responded to stinging criticism of his performances in Barca's blip in recent weeks. The Turkish international was perfectly placed to head home Denis Suarez's deflected cross home at the back post before producing a fine low finish into the far corner from Aleix Vidal's cut-back.
