Burley said: "We've not played badly at all this season but today we had all the determination and desire to outpass a quality side like Tottenham.
"We've proved we are still a very good side and confidence is still high. History is against us because records show that teams at the bottom at Christmas always go down but we're out to prove ourselves the exception.
"It's a great result and will put us in good heart for the next two home games against Leicester and Sunderland. We'll focus everything on those matches now."
George Burley was delighted by his side's performance as Ipswich grabbed only their second Premiership win of the season.
