Nikolaj Moller has begun training with Arsenal U23s this week.
The London Evening Standard says the 18-year-old arrived from Malmo on the European transfer window deadline day and this week trained with the Under-23s for the first time.
Moller has signed a four-year deal, with the option for a further 12 months, and will spend most of his time under the watchful eye of Steve Bould.
Moller arrived with the reputation of being one of Sweden's best young talents after impressing at youth level, but has played most of his football in Italy during a loan move with Serie A side Bologna where he got his nickname.
The teen has been likened to AC Milan star Zlatan Ibrahimovic.
