Krystian Bielik, one of Arsenal's January signings, could make his first-team debut against Leicester City on Tuesday night after he was withdrawn from the club's under-21 squad to face Newcastle on Monday.
The 17-year-old Polish midfielder, signed from Legia Warsaw for £2.5million, did not travel to Newcastle and instead trained with the first-team in preparation for the game at the Emirates.
Arsenal's bosses have been impressed with Bielik since his arrival and manager Arsene Wenger may reward him with a place on the bench, according to the Daily Star.
Wenger had insisted last week that both Bielik and Serge Gnabry would play in the game at St. James Park. Gnabry had been injured for 11 months due to a knee injury and the 19-year-old managed 65 minutes on his reappearance, which Arsenal won 2-1.
Alex Iwobi's strike for the Gunners was cancelled out by Dan Barlaser before Austin Lipman claimed the points for the north London side.

The first-team, meanwhile, will be desperate to return to winning ways following the weekend defeat to rivals Tottenham and nothing other than three points against Leicester will be acceptable.
Victory could be enough to propel Arsenal into the Premier League's coveted top four, and there will be serious questions asked if they are unable to overcome the bottom side.
