Seoane was appointed manager of reigning Swiss Super League champions Young Boys on 2 June 2018.

[3] Seoane, aged 39, was considered a surprise pick to succeed Adi Hütter as coach, despite guiding FC Luzern to third place in the Super League in his first full management job.

[3] Upon taking the role as Young Boys manager, Seoane pledged to continue with Hütter's playing style and keep the backroom staff in place.

However, he was sacked on 5 October 2022, due to his Leverkusen's poorest season start since their promotion in 1979.

[8] Seoane was born in Luzern, Switzerland to Galician parents and holds both Swiss and Spanish citizenship.
