Robbie Brady says it would be "beyond belief" if his away goal helps Republic of Ireland clinch a Euro 2016 spot on Monday.
Brady's 82nd-minute goal put the Republic 1-0 ahead in Friday's play-off first leg in Zenica before Edin Dzeko levelled for Bosnia-Herzegovina three minutes later.
"These are the most important games for me. Playing for my country," said the 23-year-old Norwich winger.
"To score a goal which could turn out to be important for us is beyond belief for me. I can't wait for Monday night now."
