Scott Sinclair got Celtic off to the ideal start when he scored from the penalty spot after just seven minutes.
Mikael Lustig rubbed salt into Rangers' wounds by claiming Celtic could have scored 10 at Ibrox, such was their dominance.
Celtic dominated throughout at the home of their fierce rivals and are now five matches away from ending the domestic campaign without defeat.
Wallace then went on to add that his best game at Rangers was also the 3-2 win over Celtic in the Old Firm derby in March 2012.
"Aberdeen are well clear of us, so that suggests just how much work has to be done and how much better we'll need to be next season".
Furthermore, looking at the recent matches between the two sides, Celtic have been dominant, winning 4 and drawing 1 in the 5 matches that the two sides have played since September a year ago. "The way we played for that full game was very pleasing".
"The goals we lost were poor, as were the decisions which led to them".

Comey said he didn't publicly disclose the FBI investigation into the Clinton emails until it was closed last summer. Joe Manchin, D-W.Va., said Clinton "said some horrific things, and I think, and just disgusting what she said".
Yet Caixinha insisted he was happy with the intensity levels shown by his hapless side, whose late Kenny Miller strike was of no consolation.
It did not escape Miller's notice that, of Brendan Rodgers' signings since he took over from Ronny Deila as Celtic boss last summer, only Sinclair and Moussa Dembele are regular starters and the French striker missed Saturday through injury.
"We need to make a lot of changes, we are very keen to reduce the difference", he said.
Rangers vs Celtic: What time is the game on?
A humiliation for Rangers, who may be back in the upper reaches of the SPL but now know, after a humbling season, just how big the gap is that they still need to bridge.
"It was an outstanding team performance", he told Sky Sports News.
An explosive start at Ibrox saw Celtic gifted a penalty as Myles Beerman cut down Patrick Roberts on the edge of the box with the winger running away from goal. "Our game at Ibrox last time, there was a great atmosphere with both sets of supporters, it was a good game and we came out on top and looked really strong in the game".
