Rare is the day a player earns a first start for their new team in the semifinal of a competition despite being under contract with an entirely different club during the group stage, but leave it to the new-look Club World Cup to shoehorn a new quirk into the structured soccer calendar.

João Pedro was a Brighton striker. Last decade, he spent eight years in the youth academy at Fluminense. On Tuesday, he beat Fluminense in a Club World Cup semifinal playing for Chelsea.

Chelsea's latest shiny new toy glistened on debut in the sweltering Philadelphia air during the Blues' 2-1 win over Palmeiras, and he repeated the trick on Tuesday night against former club Fluminense, sending Enzo Maresca 's men on their way to a comfortable win with a sumptuous curling effort after 18 minutes.
