New Arsenal head coach Unai Emery may have a lot of work on his hands with regards to the Arsenal first-team squad, but that has not stopped the Spanish manager from adding to and developing the Gunners' youth prospects.
The north London club announced the signings of three exciting young players on Thursday - Joel Lopez from Barcelona, Estonia Under-17 goalkeeper Karl Hein and Sunderland's exciting 16-year-old striker Sam Greenwood.
All three players have joined as first-year youth scholars and will develop their game at the Gunners' Hale End academy with a view to be playing first-team football in the future.
