Brazilian winger Estevao is out for the rest of the English season, with his participation in the World Cup in doubt, Chelsea interim boss Calum McFarlane said on Friday.

The 18-year-old prodigy suffered a Grade 4 hamstring injury and is "highly unlikely" to be ready for the start of the North American tournament on June 11, The Athletic reported on Wednesday.

The 18-year-old Brazilian emphatically won the battle of the teenage prodigies against Lamine Yamal.

Estevao scored a breathtaking solo Champions League goal to win the battle of the teenage prodigies against Lamine Yamal on Tuesday as Chelsea humbled 10-man Barcelona 3-0.

Estevao, who also scored on Saturday against Senegal, stepped up to net his fifth international goal.

At the Emirates Stadium, Brazil fans may have caught their first real glimpse of someone who is not merely the next Neymar, nor a Messi imitation, but a player whose emergence makes the idea of restoring a dynasty feel possible again.

Estevao, who has largely been limited to substitute appearances in the Premier League, gave Chelsea a cushion just one minute after coming on, setting up fellow Brazilian Joao Pedro for their second goal.

Eighteen-year-old Chelsea winger Estevao scored twice as an impressive Brazil thrashed fellow World Cup qualifiers South Korea 5-0 away in a friendly on Friday.

Paqueta and Guimaraes struck in quick succession late in the second half to put the result beyond doubt.
