Krysiak has established himself as the Grecians' number one this term, and he is grateful to Tisdale for keeping faith in his abilities despite the presence of veteran stopper Lenny Pidgeley in the Exeter squad.
"He believes in us and in the younger players. He's given me the chance which most managers won't do over the older and more experienced players," the 22-year-old told Press Association Sport. "That is good as most managers would not do that, but he is different."
Meanwhile, Krysiak suggested the return to fitness of Exeter's attacking players will help the Devon club climb the npower League One table.
The Grecians have been without forward options John O'Flynn, Daniel Nardiello and Guillem Bauza for long periods this term because of a variety of injuries. But with a fully-fit squad now at Tisdale's disposal, Krysiak thinks the only way is up for Exeter.
"We started the season with four injured strikers which was difficult for us to score goals," he said. "But we are starting to get back to where we want to be now, pressing up the league."
