In his first season in England, the South American has made a good impression so far. He may not have a regular spot into the team yet, but Kenedy has certainly demonstrated his potential and versatility since making his debut in August last year.
''I played loads of street football in my childhood back in Brazil," he recalls. "You wouldn't believe it if I told you what my feet were like after a proper game in the streets of Santa Rita!

Kenedy poses a threat going forward as well as being comfortable in defence
The left-footed attacker claims to be comfortable on either flank, in a central role up front or even as a left-back, a position that he's played in recently under Guus Hiddink.

Still only 20 years old, Kenedy became a professional player aged 17 at Fluminense. He was part of the Xerem youth system, where the likes of PSG's Thiago Silva, Real Madrid's Marcelo and the Da Silva twins Fabio and Rafael first emerged.
'It is an exciting time for me to join the English Premier League champions and I hope I can become an important player for the club,' he added. 'I very much enjoyed my time with the squad during pre-season and I am very grateful to Fluminense for allowing me this opportunity.'
The exciting forward has played just 16 games this season for the Blues
Kenedy scored six goals in eight games for Brazil under-17 as they came third at the 2013 South American Championship in Argentina.

On 30 August 2016, Kenedy joined Watford on a season-long loan after having a bid accepted from Chelsea. On 26 September 2016, Kenedy made his Watford debut in a 2–0 away defeat against Burnley, replacing Roberto Pereyra with 15 minutes remaining.
Still, it's not just fans who are prone to making poor decisions in the tattoo parlour.
"But if you look to our second half of the season you'll see that we've improved a lot. The players are together to try to make things better for the club. I'm confident Chelsea can win trophies next year."
Apparently, the Portuguese manager was convinced of his new player's capabilities to feature in the first team without being sent out on loan.
''I'll never forget my first day at Chelsea," Kenedy tells FourFourTwo. "Jose Mourinho looked at me and said: 'Let's see if you really are good, boy.'"
The Blues are paying for their slow start of the season with a melancholic end to it. PSG and Everton recently ended Guus Hiddink's hopes of avoiding a trophyless campaign.
"It's my dream to become a Chelsea regular," the youngster declares. "I'm very hungry and proud to be at one of the giant clubs of the world. It depends only on me to make a big impact here and I'm working hard to achieve it sooner rather than later."
Prepare to behold the first snap of Kenedy's new tattoo. He's helpfully posed with a picture of his lady friend, just to help us accurately compare the inky artwork with reality.
As Kenedy's new tat proves, professional players are far from immune to bad body art themselves.
During those sunny days in Brazil, there weren't trophies to dream of. The pride of winning and, above all, avoiding getting thirsty after matches was all he could ask for.
"When I say serious, I mean really serious, you know? It was our own World Cup, nothing could be more important than winning those games against my friends. However, I've drunk much more Coke than I paid it for others,'' he grins.
Kenedy - Watford (ENG)
Kenedy originally named as part of the Brazil under-20 squad for the 2015 World Cup in New Zealand, but missed the tournament with appendicitis, being replaced by Malcom as the team ended as runners-up.

Even though Kenedy is enjoying himself on and off the pitch in England, he's also looking forward to having some days off with his old friends in Brazil.
''I knew beforehand that Chelsea's youngsters normally go out on loan for a couple of seasons," Kenedy admits. "It might be good for some players, but I really wanted to stay here straight away. Luckily I could show my football ability and convince them I was worth a place in the squad."
It might not be the kind of name you expect from a Brazilian starlet, but Robert Kenedy, the versatile Chelsea youngster, is indeed a samba boy. Robert Kenedy Nunes do Nascimento was born in 1996 in the state of Minas Gerais in the south-east of Brazil.

In March 2015, Kenedy scored in three home victories for Flu in the year's Campeonato Carioca. On 18 April, in the tournament's semi-final, he missed their first attempt as they lost 9–8 in a penalty shootout to Botafogo.
But although things have been difficult for Chelsea fans, the situation could turn out to be a positive thing for Kenedy. It's hard to imagine that the 20-year-old would've enjoyed the same number of opportunities last season, when things were running much more smoothly at Stamford Bridge.
However, that wasn't the first step of his career. The dream of making a living out of football made him leave his place of birth, Santa Rita do Sapucai, in the countryside of Minas Gerais state, at just eight years old.
The 19-year-old forward arrives from his native Brazil, for whom he has played at Under-20 level.
Kenedy is now focused on securing a regular spot in the first team.
Mariappa, 29, was released by Crystal Palace in the summer after making 39 Premier League appearances for them in three seasons.
