Born in Norrköping in Sweden, Olsson started his career at IK Sleipner. When he was 13, Olsson was offered a trial at English club Chelsea, however he didn't attend and subsequently moved to IFK Norrköping. When he was 16, Olsson garnered interest by European clubs such as Juventus and Ajax, as well as domestically from IFK Göteborg. However, he signed for Arsenal in 2011 for £200,000 after having spent two previous trial periods with Arsenal. While on trial at Arsenal, he played for Arsenal's under-16s against Crystal Palace and was invited to take part in the Ferrolli Cup and the Nike Cup as a result of his performances. Olsson revealed that it was the drive of Arsenal Academy manager, Liam Brady, who persuaded Arsène Wenger to sign him, that persuaded Olsson himself to sign for Arsenal.
Olsson first played for Arsenal during their 2013 pre-season tour of the Far East. He scored his first goal for Arsenal against the Indonesia national football team at Gelora Bung Karno Stadium, Jakarta following a cross from Tomáš Rosický.
