Before every major tournament, eyes are trained on the next generation of stars set to take the football world by storm.

This year's rescheduled Copa America is no different with the likes of Ecuador midfielder Moises Caicedo, Brazil right-back Emerson Royal and Colombia forward Jaminton Campaz on the scene.

But there is still no changing of the guard as Lionel Messi, Luis Suarez and Edinson Cavani, among others, continue to dominate on the international stage.

Stats Perform looks at six players above the age of 30 and their eye-catching numbers heading into the 47th edition of the Copa America.

Lionel Messi, 33, Argentina

Messi enters the showpiece South American tournament on the back of another impressive club campaign. With 30 league goals in 2020-21, Barcelona superstar Messi has now recorded 25-plus goals in each his past 12 league seasons. Craving senior international silverware with La Albiceleste following runners-up appearances at the Copa America in 2007, 2015 and 2016 and the World Cup in 2014, Messi scored 11 LaLiga goals direct following a ball carry last season – the most of any player in Europe's top five leagues. Following a third-placed finish in 2019, Messi – the country's all-time leading scorer with 72 goals, while only Javier Mascherano (147) has earned more caps than the six-time Ballon d'Or winner (144) – will be hoping this year's tournament delivers that much-coveted international prize. Argentina are in Group A alongside matchday one opponents Chile, Uruguay, Paraguay and Bolivia.

Luis Suarez, 34, Uruguay

Suarez upstaged close friend Messi in 2020-21 after swapping Barca for Atletico Madrid. Having been forced out of Camp Nou amid concerns his best years were behind him, veteran forward Suarez found vindication and the ultimate revenge by leading to Atletico Madrid to LaLiga glory. His 21 goals were worth 21 points last season – the most of any player in the competition. Since 2011-12, only Messi (492) and Cristiano Ronaldo (411) have been directly involved in more goals in Europe's top-five leagues than Suarez (325 – 233 goals and 92 assists). Uruguay's all-time leading goalscorer (63), Suarez is far from a spent force as Oscar Tabarez's side – who are scheduled to open their campaign against Argentina – fight to win a first Copa America crown since 2011. Suarez has been directly involved in nine goals in 10 games at the Copa America (six goals and three assists).

Edinson Cavani, 34, Uruguay

Cavani and Suarez are the face of a generation that delivered the 2011 title, finished fourth at the 2010 World Cup and reached the quarter-finals at Russia 2018. Cavani joined Manchester United on a free transfer from Paris Saint-Germain at the beginning of 2020-21 and made an immediate impact at Old Trafford, finishing the season with 10 Premier League goals and 17 across all competitions – his minutes per goal ratio both in the Premier League and in all competitions the best among his team-mates (137 and 128). In the Europa League final loss to Villarreal, Cavani became just the third player aged 34 or above to score in a major European decider for an English club, after Gary McAllister (36) for Liverpool in the UEFA Cup final against Deportivo Alaves in 2000-01 and Didier Drogba (34) for Chelsea in the Champions League final versus Bayern Munich in 2011-12. Only Suarez has scored more goals for Uruguay than Cavani (51 in 118 appearances), who earned a new deal in Manchester.

Alexis Sanchez, 32, Chile

Sanchez's club career had been on a steep decline since he left Arsenal for Premier League rivals United in 2018. But the Chile star has enjoyed success at Inter. Although a squad player under former Nerazzurri coach Antonio Conte, Sanchez – who joined Inter permanently last year – scored seven goals and supplied five assists in just 12 starts last term. An option in place of regular starting duo Romelu Lukaku and Lautaro Martinez, Sanchez ranked better in shooting accuracy excluding blocks (69.6 per cent), passing accuracy (80.0), passing accuracy ending in the final third (73.5) and dribbled success rate (60.0) than both men. His big chance conversion rate (50.0) was only second to Lukaku, likewise his shot conversion rate (24.1). At international level, there is no disputing his role for Chile after leading La Roja to Copa America success in 2015 and 2016. Chile's most capped player (138) and leading goalscorer (46), Sanchez will once again carry the weight of his country this month.

Marcelo Martins, 33, Bolivia

The heart and soul of a nation? Look no further than Martins. The iconic forward stands alone as Bolivia's record holder for goals (25 in 83 appearances). Of those, 18 have come in CONMEBOL World Cup qualifying, also making Martins Bolivia's top scorer in that competition. Currently playing his football for Cruzeiro in Brazil, Martins scored three goals in the two qualifiers immediately prior to the Copa America, helping his side to earn four points. With their talisman leading the line, Bolivia – who won their only Copa America title on home soil in 1963 and lost the final when they hosted again in 1997 – are seeking to advance from the group stage for the first time since 2015. They start against Paraguay.

Paolo Guerrero, 37, Peru

Like Martins in Bolivia, Guerrero epitomises Peruvian football. The success of Peru has long been linked to the striker, who is in the history books for the most goals (38) for La Blanquirroja. Having debuted in 2004, this will be the captain's sixth Copa America appearance, having guided two-time winners Peru to third place in the 2011 and 2015 editions before securing a runners-up medal in 2019 – finishing as top scorer in all three of those tournaments. Guerrero is now the leading Copa America scorer in among active players (14) and only three shy of the all-time record (Norberto Mendez and Zizinho, both 17). While in the twilight of his career, Ricardo Gareca and Peru – who will come up against Brazil, Colombia, Ecuador and Venezuela – will be leaning on his experience across the border in Brazil.

Thiago Silva, 36, Brazil

There were some doubts about Silva's suitability to the Premier League when he saw out his PSG contract and opted to test himself with Chelsea. But the star centre-back did not look out of place in England, despite his advancing years, ending the campaign as a Champions League winner for the first time in his career. In all competitions in 2020-21, Silva led Chelsea in passing accuracy (93.0 per cent). He became Chelsea's oldest player (36 years and 249 days) to appear in a major European final, overtaking Claude Makelele against United in the 2008 Champions League decider (35 years and 93 days) as the Blues trumped Manchester City in Porto. The Selecao captain now turns his attention to Brazil's bid to claim back-to-back Copa America trophies. They have won five of the past nine.

At long last, after a 12-month delay and then so much uncertainty over the past few weeks, Copa America will start this weekend.

While the fact it is going ahead remains a bone of contention, with even Brazil players suggesting they are reluctantly playing it, Copa America is a tournament that rarely disappoints in terms of entertainment.

A bevvy of world-renowned stars such as Neymar, Luis Suarez and Lionel Messi will be hoping to make the difference.

There will also be some less-familiar faces hoping to either establish themselves or introduce their names to a wider audience.

Stats Perform has identified seven players worth keeping an eye on over the next month.

Rodrigo de Paul, 27, central midfielder - Argentina

Perhaps the odd one out here given his age, but De Paul is certainly one to keep tabs on. Having just enjoyed a wonderful individual campaign with Udinese, the creative midfielder is eager on a move and will surely be keen to impress.

He had a hand in 18 Serie A goals this term (nine goals, nine assists), while his xA value (expected assists) of 10.3 was the best in the division, the 1.3 differential suggesting De Paul was occasionally let down by poor finishing.

Further to that, he also attempted (191) and completed (122) more dribbles than anyone else, so Argentina will look to him to drive them forward from midfield.

Moises Caicedo, 19, central midfielder - Ecuador

Caicedo joined Brighton and Hove Albion in January to much fanfare from South American experts, who assured Seagulls fans they were getting a future superstar.

He's yet to make a senior appearance in England, with Graham Potter patient regarding his adaptation, but the Copa America could give fans a chance to see him in action.

A well-rounded, all-action midfielder, Caicedo was the teenager with the most goals (four), shots attempted (24), chances created (19), successful passes (748) and dribbles completed (23) in Ecuador's top flight in 2020, while his passing accuracy of 90.1 per cent was the highest among players to attempt 500 or more.

Emerson Royal, 22, right-back - Brazil

An impressive two-year spell at Real Betis has persuaded Barcelona to bring Emerson back to Camp Nou after a complicated three-way transfer in 2019.

He has proven himself to be both a dependable defender and a capable attacking outlet, his 10 assists over the past two seasons bettered by only one LaLiga defender (Jesus Navas, 13), while his 853 duels over the past two years is nearly 200 more than any other defender.

This paints a picture of an all-action defender who will work tirelessly up and down the right flank, and on the evidence of the past couple of years, it shouldn't take him too long to usurp Danilo as Brazil's primary option.

Yangel Herrera, 23, central midfielder - Venezuela

A long-term future for Herrera and parent club Manchester City looks unlikely, but he enjoyed a promising season with Granada in LaLiga – that coupled with a breakout tournament in Brazil could lead to promising suitors making their feelings known.

Herrera's a hard-working midfielder who made more tackle attempts (59) than any other Granada player this term, while it was a similar story with regards to duels (509) and duels won (261). Don't expect him to create much, but he's not shy about getting stuck in.

Jaminton Campaz, 21, left-winger - Colombia

Arguably the next big hope of the Colombian national team, Campaz only received his first call-up this month for the recent World Cup qualifiers. Although he did not get on the pitch, his inclusion in the squad was well-received among fans.

Colombia great Carlos Valderrama was among them as he urged the 21-year-old to grasp the opportunity in a post on his official Twitter account.

A livewire on the left flank, Colombia may look to his explosiveness and trickery should games remain tight in the latter stages.

Julio Enciso, 17, attacking midfielder - Paraguay

The youngest player at the 2021 Copa America, Enciso has already played 24 top-flight matches back home for Libertad and was briefly the youngest player to score in the Copa Libertadores this century with his goal against Jorge Wilstermann last year when still 16.

A good dribbler and not shy to take a shot, Enciso has been used almost everywhere across the front for Libertad and could be an interesting wildcard option for Paraguay.

Carlos Palacios, 20, right-winger - Chile

Earlier this year, Palacios made the jump to Brazil when he joined Internacional on loan from Union Espanola, where he had developed into one of Chile's most-promising young players as a lively winger.

While he's yet to score for his new club, he proved in Chile that he has a penchant for a spectacular goal one or two, while his regular appearances for Internacional have exposed him to a far greater standard of football.
