West Brom manager Roberto Di Matteo has warned his side there is never a good time to play local rivals Aston Villa.
Villa are in a slump under new manager Gerard Houllier, finding themselves in the midst of a four-game losing streak that sees them sit just five points off the bottom.
Meanwhile, newly promoted West Brom have been one of the surprise packages of the season, racking up 22 points in their opening 16 games leaving them 9th in the table.
But Di Matteo believes his in-form side should not take anything for granted at Villa Park on Saturday.
