Emery has never won at Molineux as manager of Arsenal or Villa.
"We've been together three-and-a-half years, and we've drawn twice at Molineux and lost once," said Emery. "When I was at Arsenal, we were 3-0 down at half-time (before losing 3-1).
"We beat them 1-0 earlier in the season and we didn't deserve to win. They've lost some other games, against Chelsea and Bournemouth, where they haven't deserved to lose.
"In their last home game, they drew with Arsenal, the best team in the Premier League and maybe the world.
"Everything we have analysed makes us feel it is not an easy game, and it's also a derby. They will want to show what they can do in front of their own fans."
