Pryce’s Catalan are in town for a mouth-watering clash at Langtree Park, which will be televised live by SKY Sports.
Having lost their 100% start to the season courtesy of last weekend’s 36-36 draw at Hull KR, Simmons is expecting a reaction from his squad, in only their second competitive game at the new stadium.
He told the club’s official website: “I know Leon [Pryce] is coming here and a lot of people are talking about that but I am more worried about what we do ourselves.
“The players here don’t need telling about their performance, they are upset and we have held a good positive meeting led by the senior players.
“We’ll see what the reaction is this week.”
Catalan have a good record at St Helens, having won on two of their last three visits to Merseyside, but they were heavily beaten 40-18 at the Stobart Stadium last season.
