James Roby believes St Helens have been lifted by the endeavour and appetite shown by new signing Alex Walmsley.
Forward Walmsley, 21, and will be playing in Super League for the first time this season.
Hooker Roby told BBC North West Sport: "Alex is fresh, he wants it more than anything and it's having a positive impact on the rest of the lads.
"He's come in from nowhere. The way he is training, he's pushing for a spot."
The England international continued: "I always believe that if you see others around you doing the positive thing, it will subconsciously rub off on yourself.

"Everybody's buying into everything he's brought in. It's freshened things up for a lot of people - for people like myself and Paul Wellens, who have been at St Helens for a number of years. It's nice to have these fresh ideas and different ways of training."
