McAuley believes Myhill's performances could leave Hawthorns chief Steve Clarke with a selection headache when Ben Foster returns from a foot injury.
"Boaz is a great keeper and he's a great guy to have around the place," the defender told the WBA website. "He's experienced as well which helps.
"He's been fantastic in the games he's played. He's really settled in and he's got a few clean sheets under his belt. If we can keep winning games it will make it difficult for Ben to get back in the team.
"It's not my call but Boaz has been fantastic.
"He's made saves when he's needed to.
"He's the man in possession of the jersey and he's doing very well for us."
