Arsenal manager Arsene Wenger has revealed that Krystian Bielik is unlikely to make his senior debut for the club this season.
The 17-year-old, who arrived in North London for £2m in January, recently made his first outing for the Under-18s against Norwich City.
However, despite having impressed in that encounter, Wenger does not believe that the young Pole is ready to turn out for the Gunners in the Premier League.
"He'll play for the Under-18s tomorrow [against Leicester City]. I don't think he will make his first-team debut this season," he told reporters.
Bielik joined the Gunners from Polish outfit Legia Warsaw.
