Paul Robinson is suspended for the game so the 18-year-old keeper is set to make his full debut against Manchester United and Pennant is convinced he will do a good job.
Pennant said in the Sunday Mirror: "Scott is going to be nervous but once he gets his first touch I'm sure he'll take it in his stride.
"He is a great young keeper. I think we can get a draw against Manchester United then beat Liverpool at home."
