Blackburn Rovers and Northern Ireland boss Michael O'Neill has reassured fans of both teams that taking the dual role will not affect his performance.
O'Neill took on a short-term deal at relegation-threatened Blackburn on Friday, leading many to question how it would work alongside his responsibilities of international management.
But the 56-year-old could only see positives in taking charge of the Championship side and made a big impression on Rovers fans with a 3-1 victory over Queens Park Rangers in his first game at the helm.
"A lot of people have an opinion but a lot of people have not been in my shoes as an international manager," O'Neill told BBC Radio Lancashire.
"I have the opportunity here to come work with players on a daily basis on the training ground, which I love doing. I want to help this club.
"Given the time of the season, it's feasible for me to devote the same level of care and preparation that I would do to any job.
"So, to give people reassurance, I don't think either Blackburn Rovers fans or Northern Ireland fans should have any concerns."
Rovers will be without defender Lewis Miller in their upcoming game against Preston North End on Saturday (20:00 GMT) after the Australian sustained an Achilles injury.
Having undergone surgery, the 25-year-old will miss the remainder of the season as well as the World Cup.
"Football can be a cruel game at times and there is nothing more cruel than a player being denied that opportunity," O'Neill added.
"But he's still young. He'll get future opportunities, I'm sure of that."
