On Saturday, Chelsea will take on Palmeiras in their second attempt to win the Club World Cup.
Back in 2012, the Blues were beaten in the final by Corinthians who are still the last South American team to have held the title.
Besides, Palmeiras are Corinthians' biggest rivals. They are the two oldest Sao Paulo clubs, with their rivalry known as Derby Paulista.
No wonder, then, that the Corinthians fans are going to cheer on Chelsea against Palmeiras - and some street vendors have sensed the moment as they have some Chelsea shirts ready for sale near the club's home ground:
It should not be surprising to see Tottenham or Arsenal fans supporting Palmeiras on Saturday to balance it out - although they aren't likely to be wearing the Brazilian side's shirts for that.
