St Johnstone manager Steve Lomas admitted his team’s win over Celtic was the biggest win of his managerial career.
Goals from Gregory Tade and Rowan Vine gave the Perth side their first league win of the season.
Kris Commons had fired the Hoops ahead before Saints launched a comeback.
Lomas said: "It's just rewards for the four out of the five previous games.
"We probably deserved more points from those games but we weren't clinical.
"The boys' character is never in question, we've seen it last year and this year is the same.
"But to go a goal down so early against Celtic, you think 'here we go again', but to get back in it and turn it around was superb, although I expect it from the boys.
"I truly believed it would turn and I am delighted it was against Celtic, that's for sure."
