On the day Liam Delap made his first start for Chelsea, Nicolas Jackson's response was to get himself sent off four minutes after replacing his new rival in the striker department.
Jackson was dismissed on his 24th birthday after a late, studs-up challenge on Flamengo defender Lucas Ayrton at the end of a disastrous six-minute collapse where goals from Bruno Henrique and Danilo cancelled out Pedro Neto's early strike.
Wallace Yan rounded off the scoring with a late goal as Flamengo beat the Blues 3-1 in the Club World Cup.
It was the least a confident Flamengo, led by former Chelsea defender Felipe Luis, deserved.
