In the three weeks since managerial novice Tim Sherwood replaced Andre Villas-Boas, Spurs have been knocked out of both domestic cup competitions.
But Sherwood has overseen a Premier League revival, collecting 10 out of a possible 12 points as Tottenham has climbed to within two points of the top four, in sixth place.
Looking to maintain that momentum, Sherwood made only one change from the side that won at Manchester United on Wednesday, with 19-year-old midfielder Nabil Bentaleb making his first Tottenham start.
Wenger, though, had the luxury of making five switches from the side that beat Cardiff 2-0 on New Year's Day and Arsenal still was in the ascendancy throughout.
"We had good discipline and were tight at the back," Wenger said. "With quick, sharp passing we looked dangerous."
Tottenham's best chance was squandered 10 minutes into the second half, as former Arsenal striker Emmanuel Adebayor, who was jeered throughout, struggled to make a clean connection with Aaron Lennon's cross.
As Tottenham's back-line continued to crumble, Walcott was unfortunate not to score, curling a low shot wide before being forced off when he was having a great impact leading the attack.
"He had a fighting attitude," Wenger said.
