Arsenal have confirmed that forward Gabriel Martinelli will miss the remainder of the season after undergoing surgery on a knee injury.
The 19-year-old had enjoyed an impressive first season in England having joined the Gunners from Ituano, who ply their trade in the lower leagues of Brazilian football.
It was announced on Tuesday that a training ground injury had ruled Martinelli out of Thursday's Premier League win at Southampton, but the club have now said he faces a prolonged period on the sidelines.
As part of their team news update, they described Martinelli's injury as: "Left knee. Sustained injury during training on 21 June. Successful arthroscopic procedure undertaken to repair a lesion in the cartilage of the left knee. Will not be available for the current schedule of remaining 2019/20 matches."
Martinelli has hit 10 goals from just 15 starts across all competitions for Arsenal this season, proving to be a rare bright spark in a campaign that has so far offered very little.
