Frank Klopas has taken the reins as replacement Chicago Fire coach following the sacking of Carlos de los Cobos.
The Mexican was fired this week after the Fire won just one of their opening 11 games this season and Klopas, who acted as the club's technical director, said it was not a rash decision to move the former El Salvador boss on.
''We run the soccer operation, and soccer people make soccer decisions,'' Klopas said. ''Carlos is a great human being. I have tremendous respect for him, but sometimes things don't work out.
''The decision didn't happen in one day or two days. It was a process. We had to make the right decision for the team moving forward.''
de los Cobos joined the Fire at the start of the 2010 season with the club finishing with a record of 9-12-9 before their poor start to his second term in charge.
Klopas' first game at the helm will be at home to the Seattle Sounders this weekend and he says he has faith in the playing group.
''I told them the most important thing as far as they're concerned is that I believe in them. I wouldn't have stepped in to do this if I didn't,'' he added.
