St Helens coach Mike Rush insists the Stobart Super League club will not be underestimating Oldham in Friday's Challenge Cup tie.

The club have been galvanised since Rush took control of first-team affairs from Royce Simmons, losing just once in six outings.
The Langtree Park side take on lowly Oldham on Friday and Rush has hinted he will not be giving any of his big names a breather.
Rush knows the importance of momentum and does not want his troops taking it easy ahead of returning to Super League action against Wakefield.
"We won't rest many players, if any at all," commented Rush in the St Helens Star.
"We want to keep our own form and momentum going and if you make changes for changes sake you may lose that - we don't want to do that with some big games coming up.
"There have not been that many games where we have been able to play (Paul) Wellens, (James) Roby, (Jonny) Lomax and (Lance) Hohaia together in the first 12 rounds, so why alter that.
"I am a big believer in trying to get a partnership going between our six, seven, nine and one.
"We are not resting on any laurels, nor are we saying that we have a god given right to win the games against Oldham and Wakefield.
"But we are a confident team at the minute that believes in our own ability.
"We are no mugs as much as some people have written us off and we have confidence within our group of players that we will be there at the end of the season to put in a strong challenge."
