Swansea City chairman Huw Jenkins explained to fans the sacking of Michael Laudrup.
Laudrup was shown the door last week.
In his programme notes for the game against Cardiff City, Jenkins said: "Changing a manager mid-season is not always a wise choice unless, of course, there is good cause and solid reason.
"Collectively as a board we assessed every aspect surrounding the way our first-team staff and squad was working on a day-to-day basis.
"Without going into detail, it was clear to all of our directors that the strong principles we have had at Swansea City over the last 10 years were slowly being eroded.
"Only time will tell whether the timing was right, but in the end we had to get back to basics for the betterment of Swansea City.
"We need to work as one with a strong belief that we can compete with everyone in everything we do."
