Vinicius Junior (Real Madrid) - The Brazilian, 19, starred in El Clasico, scoring the opener and generally terrifying the Barcelona defence with his pace. Still much to improve in terms of end product, but his speed and trickery underlines why Madrid paid €45 million (Dh183m) for a 16-year-old winger with limited first-team experience. Proved it was an astute piece of business during his debut season. Made his Brazil debut, belatedly given injury, in September. AFP
Phil Foden (Manchester City) - The English youngster, 19, gave a man-of-the-match display in the Carabao Cup final, portraying why Pep Guardiola once described him as the most gifted player he’s worked with (ahem … Lionel Messi). A fearless dribbler with fantastic technique, Foden is seen as heir apparent to departing City star David Silva. Excelled on Sunday when deployed wide on the right, although has started only five Premier League matches in the past two seasons. AFP
Erling Haaland (Borussia Dortmund) - The Norwegian, 19, hit the headlines last year, scoring 17 goals in 16 league appearances for RB Salzburg, adding another eight in six in the Uefa Champions League. The striker’s form prompted a move to Borussia Dortmund in January for €22.5m – the Germans met his release clause - with Haaland continuing to find the net. He struck a hat-trick in his first 23 minutes in black and yellow, and currently has 12 goals in nine games. EPA
Alphonso Davies (Bayern Munich) - The Ghana-born Canadian, 19, is an electric winger comfortable at left-back or further forward. Provided a superb display last week in Bayern’s resounding win at Chelsea in the Champions League. Transferred from Vancouver Whitecaps in July 2018 for $22m (Dh81m) – a then record in Major League Soccer – and is now considered one of the best in his position in the world. Starred for Canada at the 2017 Gold Cup. AFP
Jadon Sancho (Borussia Dortmund) - The English winger, 19, was already tipped for stardom before Dortmund recruited him from Manchester City in August 2017 – for a relatively paltry £8m (Dh37.5m). Was Europe’s lead provider last season, with 23 assists, while this campaign he has 14 assists to go with 14 goals. Pacey and an expert dribbler, has become an England regular. "He's brutally good," Dortmund CEO Michael Zorc said. "He can do things I have rarely seen." Reuters
Ansu Fati (Barcelona) - The Guinea-Bissau-born Spaniard, 17, burst onto the scene this season, scoring twice and registering one assist in his first five matches. At that stage, he was only 16, becoming the second-youngest player to feature for Barcelona. His debut goal made him the youngest scorer in the club’s history, and the third youngest in La Liga. In December, the fleet-footed winger became the youngest player to score in the Champions League, aged 17 years and 40 days. EPA
Rodrygo (Real Madrid) - The Brazilian, 19, has found his integration into the Bernabeu first team somewhat slow, but is considered a future star. A Brazil international, Rodrygo caught the eye with his dribbling and deadeye finishing. Joined from Santos in 2018 for a reported €45m, then announced his arrival by coming off the bench against Osasuna to score within a minute of his league debut. Two months later, he struck a hat-trick in the Champions League clash with Galatasaray. Reuters
Lee Kang-in (Valencia)- The South Korean, 19, was first spotted when he appeared on a reality TV show aged six. Joined Valencia’s academy in 2011 and was officially added to the first team in January last year, having already made his debut. An effervescent and versatile attacking midfielder, he registered two goals and four assists at last year’s Under 20 World Cup as South Korea finished runners-up. Lee won the Golden Ball, the award for the tournament’s best player. EPA
Mason Greenwood (Manchester United) - The English striker, 18, has been making waves for some time, the result of prolific performances for United’s under-age sides. Made his first start for the senior team in the Europa League against Astana last September – he had already appeared as a substitute in the Champions League - becoming the club’s youngest goalscorer in European competition. A product of the United youth academy, the two-footed forward has scored eight more times, including five in the Premier League. Reuters
