What's gone wrong for Chelsea talent Kendry Paez?

Attacking midfielder Kendry Paez has finally pulled on a Chelsea shirt, three years after agreeing a move to Stamford Bridge - albeit for the club's Under-21s.

Chelsea agreed a £17.27m deal to sign Paez from Ecuadorian side Independiente del Valle in 2023 when he was 16, but his development has not progressed as quickly as many expected.

Now 19, Paez made his first appearance in Chelsea colours for Cobham Next Gen, the club's newly-renamed Under-21 side, as a 12th-minute substitute in a 4-1 win away to Arsenal on Saturday.

It comes after new manager Xabi Alonso said the midfielder was "not in my plans" and Chelsea listed him as an academy player on the club website.

Chelsea explored the possibility of a loan move in English football, but Fifa regulations left the club unable to send him overseas after using all six of their available international loan slots.

With 27 caps for Ecuador, an appearance at this summer's World Cup and a reputation as one of South America's brightest young talents alongside Blues team-mate Estevao Willian, what has happened to Paez?

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.

There was one reminder of Paez's quality in the dying moments of Cobham Next Gen's (Chelsea Under-21s) defeat at Wycombe Wanderers in the EFL Trophy on Tuesday.

It was an outswinging cross from a short corner routine, which Harrison Bettoni tapped in during added time. He then put in another cross that caused havoc as Chelsea chased an equaliser in front of just 778 fans.

It was a much-needed boost for Spanish-speaking Paez, who appeared to stand alone from the other academy players before kick-off.

He did join in their warm-ups but mostly kept to himself before coming on in the 62nd minute.

Ultimately Chelsea lost, while Paez was a peripheral figure playing as a right-sided No 10, like Cole Palmer, in a system that mirrored Alonso's back-three shape.

That was until his flurry of activity late on.

Although he's not Chelsea's youngest player, Paez has already made 70 appearances for Ecuadorian side Independiente and more than 100 senior matches in total.

It's something he can fall back on in a more than salvageable situation.

Chelsea have been encouraged by his attitude, having him back in the building at Cobham where he has trained in a stable and elite environment.

There is stability around him as family attended his recent match at Wycombe.

The Blues are also now able to monitor his development more closely, while academy matches are regularly attended by scouts from across the English Football League and beyond.

There is optimism from those close to Paez that he can impress and gain a first loan move in England in January, or one of the six international loan spots will become available for him to go overseas again.

It's more than possible he can rediscover the form that attracted Chelsea in the first place and fulfil the immense potential that made him one of South America's most coveted young talents.
