When Benfica faced Bayern Munich in the UEFA Champions League in September, a loud, almost-deafening whistle from around 60,000 fans was heard when the substitute board went up in the 79th minute.
James Rodriguez's No. 11 flashed up, and as Bayern's Colombian maestro slowly walked off the pitch, the boos became even more ferocious.
James decided to respond to them by holding up five fingers to the Lisbon crowd. That led to Benfica's centre-back and captain, Jardel, rushing towards him. He had to be stopped to prevent a head-to-head confrontation, while Benfica coach Rui Vitoria remonstrated to Bayern counterpart Niko Kovac about the incident.
