Squads for the upcoming Copa America could look vastly different by the time the tournament comes around following its postponement.
The latest edition of the competition was scheduled to start in June, but the coronavirus pandemic has seen it pushed back 12 months.
Some veteran players might now fade from the picture before the Copa America gets under way next year, while other stars will have time to recover from injury.
There could also be some new faces on the scene, with a host of uncapped prospects given an extra campaign to break through.
We take a look at five players who might emerge between now and the tournament.
GABRIEL MARTINELLI (BRAZIL)
Even beyond Neymar, Roberto Firmino, Gabriel Jesus and co., Brazil have a wealth of attacking talent.
Matheus Cunha and Paulinho each starred at this year's CONMEBOL Pre-Olympic Tournament and are already plying their trade in the Bundesliga, yet the nation's most outstanding prospect might reside in London.
Gabriel Martinelli is eligible for both Brazil and Italy, but the Selecao will surely move swiftly to cap-tie the striker.

Martinelli trained with Brazil last year aged 17 after starring for Ituano, and he has continued to impress in his first season at Arsenal, scoring 10 goals in all competitions.
Further progress in the coming season would give Tite something to think about.
CRISTIAN ROMERO (ARGENTINA)
Argentina have long had problems at centre-back, with Manchester City defender Nicolas Otamendi still a regular at international level.
However, head coach Lionel Scaloni could soon have greater options to choose from, with younger talents now breaking through.
Nehuen Perez might well have gone to the 2020 Copa America, having been called up for the first time late last year after promising loan spells away from Atletico Madrid, but he could soon find himself nudged back down the pecking order.
Cristian Romero appears well-placed to establish himself, having earned a €26million move from Genoa to Juventus at the start of the season, although he returned on loan to his former club, who are enduring a testing campaign.
With Giorgio Chiellini and Leonardo Bonucci ageing, Romero should get opportunities with Juve next term - and Argentina could soon come calling.
DIEGO ROSSI (URUGUAY)
Uruguay continue to rely on a number of their veterans of previous tournaments, but this will have to change in the coming months and years - especially in attack.
Luis Suarez faced a race to be fit for the 2020 edition, while Edinson Cavani's club future is in doubt as his Paris Saint-Germain contract expires. Even Cristhian Stuani is now playing in Spain's second tier. All three are 33 years old.
And Diego Rossi should back himself to be in position to put pressure on that star trio in 12 months' time.
15+ - In 2019, LAFC's Diego Rossi became the third player since 2007 to record 15+ goals in a season prior to his 22nd birthday (Cyle Larin in 2015, Erick Torres in 2014). Starlet. #OptaXI pic.twitter.com/pjLFhQw0oZ— OptaJack (@OptaJack) October 8, 2019
Rossi left Penarol for Los Angeles FC aged 19 and has proven an instant hit in MLS, scoring 29 goals in 68 regular-season appearances, helping his club win the 2019 Supporters' Shield.
LAFC general manager John Thorrington has spoken of "significant interest" in Rossi from Europe, and such a move would give the forward a great chance of making the grade for Uruguay.
JORGE CARRASCAL (COLOMBIA)
Rossi's LAFC team-mates Eddie Segura and Eduard Atuesta both appear set for first Colombia caps, but Jorge Carrascal might now have nudged to the front of that queue.
A tricky winger who debuted for Millonarios at just 16, Carrascal initially struggled after joining River Plate on loan from Ukraine's Karpaty Lviv last year.
However, Carrascal improved as the season went on, earning a permanent switch to River - and, crucially, a call-up to the Colombia Under-23s.
Representing his country at youth level for the first time since 2015, the 21-year-old scored in each of his first three games at the Pre-Olympic Tournament and started all seven matches.
A return to the River Plate XI this year could see Carrascal earn a senior Colombia call-up.
It might seem a long shot for a player who has yet to feature for Real Madrid's first team and started only twice at the Pre-Olympic Tournament to be playing for Brazil's senior side in just over a year's time.
But Reinier will have the benefit of 12 months in the limelight at one of the world's biggest clubs.
After signing from Flamengo for €30m, Reinier netted a brace in just his third Castilla appearance - his final match before the coronavirus crisis intervened.

The pre-season will be key if the 18-year-old is to get a chance at Madrid in 2020-21, and there is no reason why he could not then do enough to catch Tite's eye.
Vinicius Junior made a big-money move from Flamengo to Madrid in 2018 and had debuted for Brazil within 12 months of his LaLiga bow. The path is clear.
