Siegrist is now preparing for the London Olympics.
"He comes across as a confident sort of guy, which is what you need to be a goalkeeper, but not too confident," said Ireland keeper Given to the Express & Star.
"He's keen to learn, which is important. He's got little things he needs to improve on, but he knows that himself.
"Benji's a big guy, he's a confident guy and I think it's good that Terry Genoe's working with him and helping him to improve. I think he's keen to listen as well which is important and hopefully he'll have a big future with us.
"He's only 20 so at that age I don't think he should expect too much. But with Terry and the senior lads like myself and Andy Marshall coaching him and helping him learn, I think he should be in safe hands.
"Coming on the first-team trips has been good experience for him and he was coming out and helping to warm us up before games last season. It will give him a good feel for things."
