Arsenal were training on Friday ahead of the Premier League match against Leicester City on Saturday evening.
The North London outfit will head into the game against Leicester at the King Power Stadium on the back of a 4-3 home defeat to Liverpool.
The performance of the Gunners against the Reds at the Emirates Stadium last week was disappointing.
Arsenal looked defensively vulnerable, and manager Arsene Wenger will want his players to do much better against Premier League champions Leicester on Saturday evening.
The Arsenal players were training hard on Friday afternoon, and among those who attended the session was Krystian Bielik (see photo above).
Bielik joined the North London club back in January 2015 as a 17-year-old from Legia Warsaw.
The youngster arrived at the Emirates Stadium with a strong reputation, but he has yet to make a notable impact.
Now 18, the Poland Under-18 international has yet to make an appearance in the Premier League for Arsenal.
Bielik is a talented young footballer who can play as a centre-back or as a defensive midfielder.
