St Helens coach Keiron Cunningham says they’ll know what to expect when they take on their former half-back Luke Walsh and Catalans at the weekend.
Walsh, 29, departed the Totally Wicked Stadium after three years in the close season and has been an ever present for the Dragons this term.
He will come up against his former employers, while Saints back-rower Zeb Taia will also play against one of his old clubs.
Cunningham said: “Walshy is a professional, he plays well at whichever club he plays for and he did a good job for us.
“Unfortunately we parted company and both went in different directions.
“We all know what Walshy brings and he organises and kicks as well as he does so we know he’s going to be a threat and he’ll influence what they do.
“We’ve got to be smart with what we do about Walshy, but we’re not a bad side ourselves.
“I keep saying this, and whether people believe me or not is a different thing, but we’re not a bad side and when we get going and hit our straps we’re going to trouble a lot of teams.”
St Helens have managed just one win this season, while the Dragons were beaten last week at Leeds having drawn with Widnes the week before.
