Thomas Tuchel has sent a warning to Arsenal left-back Myles Lewis-Skelly despite naming the youngster in his latest England squad.
The 19-year-old has been called up to Tuchel's 24-player squad for the upcoming friendly against Wales and World Cup qualifier in Latvia this month.
The academy graduate was thrown into the deep end last season amid an injury crisis to Arteta's side and rose to the opportunity.
He racked up 15 league starts in the second half of last season, and had standout performances in the Champions League quarter-finals against Real Madrid.
