"The time and memories from MFF I will have with me for the rest of my life. Now I'm going out on new adventures, but before that, I want to extend a big thank you to the city, the team, the club, but above all the supporters who are always behind us. Until we meet again", says Nanasi in a statement.
Nanasi signed an A-team contract with Malmö in 2020. Last season, the young midfielder established himself in the team and has since grown into a key player for the reigning champions.
"It's been very fun to see Sebastian develop into one of Allsvenskan's best players. There has been a long time with many rumors and hard pressure about him leaving earlier, but Sebbe has wanted to stay and play as long as he can and has managed to keep focus all the way", says Malmö's sports manager Daniel Andersson.
This season, Nanasi has scored six goals and made nine assists in 17 appearances in Allsvenskan.
Strasbourg finished 13th in the French league last season and started this season with a draw against Montpellier. The club has, among other things, the same owner as the English giant club Chelsea, and is part of their multi-club project.
