Wotton is Devonshire born and bred and as a former Plymouth captain the game means more than most, but he knows that Saints have a tough test.
"First and foremost, Paul Tisdale has done an amazing job there because it wasn't so long ago that Exeter were in the Conference," he told the club's official website.
"Being a Plymouth boy and a part of the area for so many years it's no harm for me to say that I'm really glad of where Exeter are because Devon needs three clubs in the Football League.
"I have been impressed with what they have done, they're doing really well and they play football in the right way, so we'll have to be on our game on Boxing Day. It's a game we're looking forward to, but so far Exeter have done really well."
