After scoring twice and providing two assists in 13 appearances, supporters were hoping to see the Brazilian carry that form into the new campaign, although it's safe to say the 22-year-old has endured a disastrous start to the season.
Kenedy spurned a chance of an equaliser against Tottenham on the opening day, before escaping a red card and missing an injury time penalty to win against Cardiff. And his latest display in the 3-1 defeat to Nottingham Forest in the Carabao Cup second round have led to many fans taking to Twitter to unload their frustrations.
Here's what they've had to say:
The poor form of the Chelsea loanee, who was unable to play against his parent club during the Magpies' recent 2-1 defeat to the Blues, has reflected Newcastle's start to the season in which they have earned one point from their opening three games in the Premier League, and are now already out of one domestic cup.
Upon the backdrop of a frustrating transfer window with limited funds available, Rafael Benitez certainly has a lot to sort out so soon into the new season.
