Paez is a record breaker and a headline maker.
He became the youngest debutant and goalscorer in Ecuadorian top-flight history at the age of 15 before making his debut in the Copa Libertadores, South America’s equivalent of the Champions League, later that same season.
Later in 2023, aged 16 years and 131 days, he made his second appearance for Ecuador, becoming the second-youngest South American international to feature in World Cup qualifying after Diego Maradona.
A month later, he became the youngest South American to score in a World Cup qualifier in a 2-1 win away to Bolivia.
It was understandable, therefore, that Chelsea believed the attacker, who had two international goals and 18 caps when they agreed to sign him, was destined for big things.
Chelsea allowed him to train regularly with the first team before he was officially eligible to join the club following his 18th birthday.
They also provided security for Paez, his family and the family of international team-mate Moises Caicedo after violence broke out in Ecuador in early 2024.
A few months later, Paez was filmed in a New York strip club while away on international duty.
He initially impressed on loan at Chelsea’s sister club Strasbourg by winning September’s Young Player of the Month award in the French top flight, but then came in for criticism from then-manager Liam Rosenior.
“We expect more, clearly,” Rosenior said later that season. “I’m tired of using the excuse of the player’s youth.”
Despite Strasbourg’s links to Chelsea through their shared ownership, the loan was cut short after one goal in 21 appearances. Instead, he joined Argentine giants River Plate on a two-year loan spell.
Sources in Argentina expressed similar concerns about his attitude when asked by BBC Sport. They point to a disappointing display in the 1-0 Superclasico defeat by fierce rivals Boca Juniors at the Monumental in April.
Shortly afterwards, Paez was named by club president Stefano Di Carlo as one of 15 players training away from River Plate’s first team, although other sources felt he could have been given more opportunities.
His loan ended by mutual consent after Paez scored once in 14 appearances in 461 minutes for River Plate.
Ahead of the international break, concern has been expressed in Ecuador, having built him up as the country’s next great attacking talent.
Michel Deller, the owner of Independiente, told Hincha Amarillo: “He’s like a son to us. We care about him deeply.
“He’s a good kid who’s had a tough time and has made decisions that have complicated his life.
“We are always hopeful he’ll show his exceptional talent one again but right now, it’s up to him to decide what to do with his life.”
These concerns are not dismissed completely by Chelsea or Paez’s environment. However, there is a belief they are grossly overstated, highlighting he is owed time to grow as a player and person.
