Matthews, 32, shared the heartbreak at Wembley when Crystal Palace ended Watford's Premier League chances by scoring two extra time goals in the play-off final back in May.
"It would have given the town a feel-good factor if we had been promoted. But if we don't lose heart and keep our best players, there's no reason why we can't go up next season," said the middleweight.
"I hope the people of Watford get behind me the way they have supported the football team."
When Matthews met Sneidze back in March, the fight was ruled a technical draw in the third round after an accidental clash of heads left Matthews cut. This is the only blemish on his eight-fight record. With six of his seven wins coming inside the distance, Matthews was confident of making it to 8-0 before the head clash scuppered his efforts.
"I didn't really do much wrong in the first fight. I was stepping up the pace every round and by the fourth or fifth I think I would have got him out of there," he said.
"I'm annoyed because I was boxing well and ended up with a draw - and his supporters were celebrating as if he had won.
"I'm hoping for an early night in the rematch, but it won't be a walkover. He's tall, can box and move and is awkward, but I have the skills to get to him. I can find the gaps and put him away."
