Southampton defender Dejan Lovren has no concerns over Artur Boruc heading into their clash with Chelsea.
Boruc was responsible for Arsenal's opening goal in defeat at the Emirates last week.
"I think now that mistakes happen every time, we are all people," said Lovren.
"It was a really stupid mistake but we didn't do anything special this week [in training], we were doing our job like every week.
"So we need to just keep our heads up and play our own game on Sunday.
"We are behind him [Boruc] because we are a team and we need to be all together in this, when we make mistakes we make them together not just as one."
