Nikolaos 'Nikos' Tsoumanis (Greek, Modern (1453-);: Νικόλαος 'Νίκος' Τσουμάνης; 8 June 1990 – October 2021) was a Greek professional footballer who played as a left-back.[1]
Tsoumanis left Panthrakikos as he did not renew his contract to join Veria on 9 July 2015.[2] He later signed with major Greek club, Aris.
Tsoumanis was found dead in his car on the morning of 5 October 2021. The medical examiner believed the cause of death to be suffocation. Police initially suspected "foul play" as his hands were bound.[3] However, following further examination, Tsoumanis's death was ruled to be an accident.[4]
