Football tends to take a back seat during the Olympic Games – both because there are so many other sports vying for attention and because the major nations do not regard it as a priority. The under-23 tournament has produced some memorable moments in the past, but the reality is that, in this era of soaring bank balances and packed schedules, the Games are viewed by many as an inconvenience.
The exception that proves the rule is Brazil, who are taking the competition very seriously indeed. Their priorities for the summer were established early in the year when it was decided Neymar would be left out of the squad for the Copa América Centenario so that he could appear at Rio 2016. He is, by some margin, the biggest star present at the tournament, but by no means will this be a one-man show; Brazil's squad boasts plenty of other talent, especially in attacking areas.
