AmaZulu head coach Benni McCarthy believes his charges suffered a 1-0 defeat to relegation threatened side Baroka FC due to the stadium change.
Usuthu have played a chunk of their home matches at Kings Park this season and have gone on a 16-match unbeaten streak.
But on Tuesday, the KwaZulu-Natal side were forced to return to their home ground, King Zwelithini Stadium, where Baroka handed McCarthy’s side their first league loss in four months.
"I think psychologically moving the game away from Kings Park affected the team a little bit," explained McCarthy.
"Obviously, this used to be the clubs home ground but this season, we have played every game at Kings Park. We became quite accustomed to the stadium and the pitch.
"We were very familiar with everything. We have got some brilliant results there and then you have your home game moved to another stadium where you haven't played all season.
"It gives the opposition an opening to get in, but today the opposition team was very physical."
