Without talismanic half back Chris Sandow, Warrington have lost their last two games and Westerman wants to get back to winning ways with a win over their local rivals.
“It’s a derby game with a big crowd, everyone will be buzzing and there’s no better way of getting back on the horse than winning a ‘derby’,” Westerman told the Warrington Guardian.
“We’ve been really good in previous weeks and have scored plenty of points so we know that, as a team, Huddersfield wasn’t good enough and we all accepted that.
“We sat down after and we knew what to work on this week. We started on Sunday and have had a couple of big days to crack on with putting it right.
“They’ve lost a few games as well but they’ve got a lot of players back. We’re itching to get back to how we were and if we carry out what we’ve been doing in practice we will do.”
