Andy appeared as a replacement in last Friday's win over Bristol but is in the starting XV that travel to take on high-flying Sale.
"The dream ticket is to stay up and get a new contract," said Andy, who has joined Leeds on a short-term deal having turned down an offer from Castres Olympique. "I want to stay, definitely. I am basically on trial. I'm going to be unemployed in June so I've got to pull my finger out. I've been very impressed with what I've seen so far.
"Leeds have been making a lot of line-break and I am looking forward to getting on the end of a few of them."
Andy was deemed surplus to requirements at Glasgow and released early from his contract.
"Until I got injured in the autumn, I was starting every game for Glasgow," said the former Wigan, Swinton, Halifax and Widnes rugby league player. "But when I came back, I was on the bench or not even in the 22. They said it was because my contract was up in the summer, and they were not going to renew it – three senior centres were already contracted for next season.
"They said they would not stand in my way, even though I started the last couple of games."
