Youth career Nyman was born in
Norrköping and grew up close to the
IFK Norrköping home stadium. He joined the youth ranks of the club at five years of age and growing up he worked at the home games both as a
ball boy and with selling candy. Eventually he also joined the singing section during the games.
IFK Norrköping Nyman moved up to play in IFK Norrköping's first team in 2010 where he featured in three games, scoring each time. His third and final goal helped secure the club's promotion to
Allsvenskan. After the season, he was given the "Youth Player of the Year" award. The following year he made his Allsvenskan debut but was also sent on loan to
third tier club
IF Sylvia to get more playing time. In 2012, he had his big breakthrough at the highest Swedish level, scoring 8 goals in 29 games for Norrköping. During the start of the
2013 Allsvenskan season Nyman struggled to perform after suffering from unknown stomach problems. After a successful first half of the
2015 Allsvenskan Norrköping turned down two bids from
FC Groningen and
Osmanlıspor to buy Nyman during the summer. The club cited their ambition to win the league as the reason for keeping him and at the end of the year they did end up becoming champions for the first time in 26 years. He played a key role in their success and he was arguably their best player.
Eintracht Braunschweig In August 2016, Nyman transferred to German
2. Bundesliga club
Eintracht Braunschweig.
Return to IFK Norrköping In January 2019, Nyman returned to IFK Norrköping having agreed a four-year contract. ==International career==
