The 23-year-old began his career with Portsmouth and grew up in the area and has described the draw as "unbelievable".
"Obviously I'm excited being a Pompey fan and growing up in the area," he told BBC Radio Solent. "It's a great draw for me personally but also the club.
"When we played them in the league last season it was a great atmosphere and I'm sure it will be again. It's a derby so it'll be a tough test but I'm sure if we're at the races we'll be fine."
