The new-look, promoted Baggies had the better of the second half in a 1-1 draw against a Villa side aiming for the top six this season.
Gary Megson's side included summer arrivals Kanu, Jonathan Greening, Darren Purse and Hungarian Zoltan Gera and won favourable reports in Monday's press.
"I thought they played well against Aston Villa because Villa are a good team," said Jacques.
"I don't know the team that will play against us on Wednesday but West Brom have good players.
"I know Kanu and I watched on the television in attack, Horsfield is very strong, Clement in midfield has a good left foot and and Mr Megson is a manager with good fighting spirit.
"A promoted team always wants to make a good start to the championship.
"Each game for us this season is difficult and I think we will have a good team against us at West Brom. However, I hope to get a good result."
Jacques Santini was impressed with what he saw of West Brom against Aston Villa on Sunday.
