He was originally a midfielder before national coach Clemens Westerhof converted him to play left back. His club career in Europe was largely unsuccessful, and Iroha was allocated to San Jose Clash in 1996. The next season, he was traded to D.C. United, where he won the league title. After a move to Spanish side Elche CF in 1997, he moved to Watford in December 1998, playing 10 games for the Hertfordshire side. A problem with bunions forced him to the sidelines, and he retired in March 2000.
After retiring, he returned to the USA to coach in the youth department of FC Dallas. Most recently, he was an assistant with the Nigerian U-17 team that won the 2007 FIFA U-17 World Cup and head coach of Nigeria's Dolphins FC. He currently is on the staff of Heartland of Owerri.
