Borys Tashchy

Tashchy was born in Odesa. He was sold by his original club Chornomorets Odesa to the Latvian side JFK Olimps on 22 August 2011, and the very next day Olimps re-sold him to Dynamo Moscow. Dynamo's general director Roman Dyakov could not explain why they did not directly buy him from Chornomorets, citing confidentiality, and Serhiy Kernitsky, Chornomorets' vice-president was perplexed at this scheme as the transfer price given by Chornomorets would be the same for Dynamo as it was for Olimps.

Tashchy represented Ukraine in all national selections from U16 to U21. Due to his Bessarabian Bulgarian roots, in 2014 he received a Bulgarian passport making him eligible for the Bulgaria national football team. On 28 March 2016, Bulgarian media reported that Borys had already spoken with BFU officials and had expressed his desire to represent Bulgaria. Petev once again confirmed that Tashchy will play for Bulgaria on 27 May 2016, but he couldn't join the team for the Kirin Cup due to paper problems. The process of finalizing his paperwork to play for Bulgaria was put to a halt after Petar Houbchev succeeded Petev as manager of the national side.
