Kolkata: Atletico de Kolkata (ATK) striker Iain Hume on Wednesday said the lack of ethics towards the end ruined his side's 2-1 victory over Chennaiyin FC in the second leg of the Indian Super League (ISL) semifinal here on Wednesday.

Even though the hosts won the game, they crashed out of the tournament on aggregate (4-2) as Chennaiyin had won the first leg 3-0 in Pune.
