“It is disappointing but what can we do,” he said after the match at Moses Mabhida Stadium.
“We gave our all in this game but ended up losing.”
“These are results we did not desire, but we soldier on.”
Usuthu started on a high as they drew first blood with new signing, Mbulelo Mabizela, heading them into the lead.
But Pirates striking pair of Lehlohonolo Majoro each scored to see them leave the Durban venue as victors.
Barker’s great disappointment stems from the fact that Usuthu are at the bottom of the PSL standings, having collected only nine points after 17 matches.
The former University of Pretoria coach said there were lot of positives his team drew from this match.
“I think we have a lot of good things which came out from this game,” he said.
“I was also impressed with the commitment showed by the players.
“They showed a good work ethic.”
Barker said given their position on the table, his team would struggle with the smallest of things.
“We have to bounce back,” he said.
“It was small things which did not go away and these happen when you in a position like ours.”
