McAuley will play his fourth successive game alongside Olsson on Monday against Liverpool after the Swede's return from injury.
"Jonas is a massive player for the club and, when he's out there, he's 100 per cent committed," he told the WBA website.
"A centre-back partnership is an important thing and we trust each other.
"We want to develop it more. We're both disappointed we've conceded a lot of goals in the last few weeks and want to get back to being strong as a core at the back.
"Hopefully, we can help the team get the results we need."
