He does not plan to rotate his squad as they prepare for two games in three days, with Newport County AFC visiting Whaddon Road on Sunday.
Buckle said that a decision over the future of Raffa De Vita will be made after the Exeter game, with the Italian midfielder's initial contract with the Robins due to expire before the visit of Newport.
Buckle spent four spells with Exeter as a player and then a coach, while his assistant Rob Edwards and Robins skipper Matt Taylor are also both former Grecians players.
"I had good times at Exeter and came through the system there in terms of coaching," Buckle said. "It’s a very good club and I've played against Paul Tisdale's teams a few times, but things have changed there now.
"They have been on a good run and there are exactly where they want to be, with some young players doing well along with experience at the back too.
"We'll be well prepared, paying respect to their strengths and it's all about putting in an away performance, being solid and taking opportunities when they come.
"Paul has done really well at Exeter and it's a sensible club. He is the second longest serving manager in the country and I am sure his proud of that."
