Chelsea's newest signing Geovany Quenda hopes to follow in the footsteps of Cristiano Ronaldo by leaving Sporting's academy for the challenge and exposure of the Premier League.

Often compared stylistically to Arsenal winger Bukayo Saka, Quenda's journey began with an episode that has since become part of his personal folklore.

Arriving at an early training session at grassroots club Damaiense wearing jeans and shoes, he was initially told he could not take part.

But after producing an effortless first touch and dribble when the ball came his way, coach Ana Correia persuaded club officials to "make an exception" for Quenda, as she later recalled in an interview with Sabado.

Quenda's path to the top was far from conventional. Born in Guinea-Bissau, he moved to Portugal at the age of seven and had to adapt quickly to a new environment.

That journey took him from the Damaiense's under-10s to Benfica's academy before he joined city rivals Sporting, where his development propelled him to prominence in Portuguese football.

Now at Chelsea, having reportedly agreed to join as far back as March 2025 but only just formally unveiled on a contract until 2034, the Portugal Under-21 international has the opportunity to showcase his talent on an even bigger stage.

When Quenda joined Chelsea, he was accompanied by his father, mother, sisters, friends, agents and his godfather Basaula Lemba, a former top-flight footballer in Portugal who also won 10 caps for Zaire.

Lemba played an important role in Quenda's early development before Benfica brought him into their academy system in 2017.

Sporting and Porto had also been tracking him at the time, according to former youth coach Fabio Roque.

"We saw him as an under-10 player playing against us for Benfica," Roque told BBC Sport.

"We knew from our scouting team that he was a good player and had tracked his progress through the Portuguese Football Federation website.

"He was incredible and different. His discipline was not always great and he was still raw, but his attitude was excellent. He was demanding of himself, confident, unpredictable, brave and had a great relationship with the ball."

There was a "non-aggression pact" between Portugal's three biggest clubs - Benfica, Sporting and Porto - but after Quenda scored against Sporting in a key match for Benfica, he eventually made what Roque described as a "natural" move to Sporting.

From 2019, when he switched academies, the torment started to work the other way.

"I remember one match against Benfica - a very important game," Roque said.

"It was a difficult week before Christmas. We'd just suffered a heavy defeat and our captain got injured.

"Emotions were high. Fifteen minutes into the match we had a player sent off. We had to adapt, but Geovany and the rest of the team kept competing, held on at 0-0 and showed the mentality they had.

"Then I remember walking towards the dressing room at half-time and Geovany put his hand on my shoulder and said: 'It's OK, we're going to win.'

"That moment gave us all confidence. And we did win. From a corner, the ball broke to Geovany and he calmly placed it into the net.

"It was a moment of personality and belief. It showed who Geovany really is. In that moment, I thought: 'This guy is special.'"

Eventually, Quenda progressed into the under-23s under Tiago Teixeira.

"Everyone talked about him. Everyone said he was one of the most talented players in the academy," Teixeira told BBC Sport.

"We wanted him to develop step by step, but he could have made his debut sooner.

"I remember one training session when we were practising set-pieces and free-kicks. We joked that he could not score from a free-kick.

"Then he scored four or five in a row, smiled and said: 'OK, finished for me.'"

Although Quenda joins a canon of great Sporting wingers, including Ronaldo, Luis Figo and Nani, his former coach believes he most closely resembles Arsenal and England forward Bukayo Saka.

"It's his explosiveness, his ability to play inside, protect the ball, his unpredictability and his creativity," Roque said.

"Defensively, Geovany might even be stronger than Saka at this stage. Bukayo is, of course, already performing consistently in a highly competitive league. But his running, crossing and final pass remind me a lot of Saka."

Roque added: "He's one of the most impressive players I've seen. Among players born in 2007, he is one of the best in the world, alongside Lamine Yamal and Estevao. My expectations are very high, but I know it is a long career."

By the age of 16, Quenda was training with Ruben Amorim's first-team squad before the coach left Sporting for Manchester United, and he soon began breaking records.

The first came when he scored 24 minutes into his debut against Porto, becoming the youngest player to score in the Portuguese Super Cup.

He later became Sporting's youngest player to start and score in the Champions League, surpassed Ronaldo's record as the youngest goalscorer in Liga Portugal and established himself as a first-team regular at the age of 17.

"Saka is more direct and faster," Teixeira added. "But I think Quenda may be better when playing inside. It is clear he is a once-in-a-decade talent for an academy."

Quenda has had a lengthy lead-in to his move to Chelsea, spending his time at biweekly English lessons and building physical strength to adapt to the demands of the Premier League through additional training and nutritional work.

However, after working to ensure he finished his final season at Sporting strongly, he suffered a broken fifth metatarsal (a bone on the outer edge of the foot) that kept him sidelined for four months. His side finished second and lost the cup final to minnows Torreense.

During that period, he completed much of his rehabilitation at Chelsea's Cobham training ground, where he spoke regularly with then-manager Liam Rosenior and several players, including compatriots Pedro Neto and Dario Essugo.

Quenda also quietly attended matches at Stamford Bridge during this time, while avoiding being seen.

Sources close to Quenda say he is targeting a regular first-team role at Chelsea and hopes to make his senior Portugal debut in the near future.

Although Chelsea's squad are not due to return until Thursday, Quenda reported back early, along with a small number of other players, to gain a head start on his preparations.

Chelsea are adapting their squad with Quenda partly in mind. Alejandro Garnacho is for sale and academy winger Jesse Derry is set to join Sporting to create space, but Quenda may also be used at wing-back, which could be a good fit for new manager Xabi Alonso, having used deeper wide players at Bayer Leverkusen.
