Arsenal have completed the signing of 18-year-old striker Nikolaj Moller from Malmo for a fee of around £450,000.
Moller is known for his strength and speed and has been a prolific goalscorer at youth level.
After completing his medical on Monday, the Gunners eventually announced the signing a day after deadline day.
The young Swede has reportedly signed a four-year deal and will join up with Steve Bould's U23s side, not the senior side.
He has previously been involved in the youth set-up at Bologna.
The Gunners have stepped up their youth recruitment this summer as in addition to Moller they have signed George Lewis, Tim Akinola and Jonathan Dinzeyi, while they are close to a deal for Hertha's Omar Rekik.
It was a busy transfer deadline day for Arsenal, as after they failed in their pursuit of Houssem Aouar they successfully completed a deal for Atletico Madrid's Thomas Partey after triggering his £45m release clause.
