However, the point has seen them stay behind Chelsea in fifth place in the table on goal difference.
"We did ever so well in the first half, 10 shots against their two," Villas-Boas told BBC Sport. "The problem is that when we came back on after half time we thought we were in control and Wigan scored almost straight away and that really shook our confidence.
"It seemed to be against the run of play, but it is good to salvage a point, hopefully it can turn out to be an important point."
Tottenham return to league action next Saturday when they welcome Southampton to White Hart Lane.
