The Liverpool star, who scored his first goal for the national team in the recent 2-0 win over Mexico, has been given the number 21 shirt that he wore in that match for Brazil's Copa America challenge, indicating that he is unlikely to be considered a first choice starter initially.
Of course, judging starting lineups by allocated shirt numbers isn't the most accurate of strategies, but it tends to be the case that squads for international tournaments function from 1-11 unless there are any players that favour a particular number.
The talented playmaker has had a number of shirt numbers in his short career, as most youngsters tend to have, adopting number 29 when he first joined Inter in 2010, then moving to number 19 for the next season.
But it is at Liverpool that he was first given the number that he would have likely been dreaming of since a child, the number 10 shirt that befitted his playing style.
Coutinho may struggle to ever get hold of that shirt for the national team, with Barcelona star Neymar currently very much in possession of the famous shirt once worn by the likes of Pele and Ronaldinho.
The upcoming challenge for the 22-year-old, having found a role in the Brazil squad, will be seizing any chance that comes his way in the tournament in Chile, in the hope of ascending those shirt numbers towards a first team spot.
Other Premier League players set to feature in the tournament are Chelsea duo Filipe Luis and Willian and Manchester City midfielder Fernandinho.

4) David Luiz
6) Filipe Luis
