Andre Savelio says Warrington will be tested tonight when they host Castleford at the Halliwell J0nes Stadium.
Savelio knows the inner workings of the Tigers well after spending part of the 2016 season on loan at the Jungle.
The back-rower signed for Warrington from St Helens at the end of last year.
“They’re a good team aren’t they,” Savelio told Love Rugby League.
“They’ve started the year well with that win over Leigh and I finished the year there last year.
“There’s a lot of talented players there and they’ll be looking to have a big season and get two from two tonight.
“There’s a few boys here that have been at Cas, like Daz Clark. We’ve all been giving the ins and outs on them, talked up their threats.
“Other than that we’ve just been focusing on ourselves, just backing up the performance against Brisbane after a poor start at Catalans.
“Hopefully coming out and doing the same again.”
