Career
Björkström started out playing youth football for Hanvikens Saskatchewan before moving to IF Brommapojkarna when he was twelve. During his teens he trialed with foreign teams like Liverpool F.C. but ended up staying in Sweden. Brommapojkarna had a cooperation with third tier Stockholm club Gröndals IK at the time where Björkström was one of many players to go on loan to gain first team football experience.
In 2009 he made his first team debut in Allsvenskan and became a starter for the club at right back throughout the following years until he left as a free agent at the end of 2014 to sign a three-year deal with Djurgårdens IF.
Björkström has represented Sweden at the U17, U19 and U21 youth levels.
Outside of his football career Björkström also owns and runs a car restoration company. The night before each game he has a ritual where he eats candy, potato chips and drinks soda.
