Having arrived at the club last week on a deal until the end of the current campaign, with a deal with Canterbury Bulldogs already signed for next season, Chisholm played his first game for Rovers in the defeat at St Helens.
“Judging by my one game that I’ve just played, it was heaps tougher to come over and play Super League, heaps more physical,” he told the Hull Daily Mail.
“It’s a chance to impress everybody back home while over here. There’s nothing secure for 2017, so whatever happens over there I’m taking this as an opportunity to show everybody what I can do.”
Next up for Chisholm and Rovers is a Challenge Cup semi-final against Warrington at Headingley on Saturday afternoon.
The French international is excited to experience the magic of the Cup, and he is not too fussed what position he plays.
“I don’t know too much about the Challenge Cup, but I know of Wembley and it’s massive. It’s going to be a big crowd at the weekend for sure,” he added.
“I’ve been playing in the halves mostly but I can play full-back and I can add that extra link in the halves too.
“My running game is pretty solid and I’m definitely comfortable at the back.”
