The Saddlers brushed aside their Midlands neighbours 4-0 in front of a packed Banks's Stadium to extend their unbeaten run to 12 games and move to within three points of the play-off places.
Fourth-placed Sheffield United, who are just four points ahead in the table, are the visitors on Saturday in what is promising to be a crunch promotion clash and Westcarr, who bagged a brace to help see off the Sky Blues, insists belief is a fixture within the Walsall dressing room.
"Games like this (versus Coventry) in front of a big crowd and with a great atmosphere are always good and we're expecting more of the same against Sheffield United on Saturday," the forward told the club's official website. "Hopefully our fans will turn up in good numbers again and really get behind us.
"The belief is there, we've always stuck to what we're doing and now we'll take each game as it comes between now and the end of the season and see where it takes us.
"At this stage of the season every game is tough, be it against Sheffield United who are up there challenging for promotion or Scunthorpe, who we face the following week, who are battling for their lives near the bottom.
"If we can play to our ability then I would back us to beat anyone in this league.
"You can be sure that we'll be focused and prepared to work hard in order to keep getting our rewards."
