Rodriguez left the Clarets 18 months ago.
He told the Daily Echo: "I'll obviously be happy to score a goal but it's my old club.
"When the draw came through I had a lot of texts and phone calls from family and mates. It's going to be a great game.
"Moving away from family and friends I've grown up with all my life was quite hard but in time it's got a lot better and at the moment I'm loving life down here. "I obviously still miss home, that's part of it, but they enjoy coming down here a lot and it's nice to be living in a great place.
"My main focus down here is football, that's helped me and the club's helped me massively to improve as a player since I've been here.
"When I first came here I realised how fit the lads were and everything that goes with the training is really hard.
"It's something you want to improve because in the Premiership you need to be as athletic as you can be."
