The Jambos boss said that his team's second win on the spin has lifted everyone at the club following a troubled first half of the season.
"I thought the character was there in abundance again, we've shown it all season," Sky Sports News quotes him as saying. "We've had a lot of lows but this week has been great for us.
"I think you can see that it gives everyone a lift, not just myself and the backroom team but the players and the supporters.
"It has been a very difficult season for us but I have been over the moon with the way the players have performed."
Hearts remain rooted to the foot of the table having started the season with a negative points tally due to their financial issues.
