The Blues came back from a goal down to beat the Villans 2-1 at Goodison Park.
"[The win] was the most satisfying victory of the season," he told reporters.
"We were cagey in the first half [and after the goal] it became a real test of character. Today we were more concerned about the tactical aspect than enjoying our football.
"To win it with that moment of brilliance from Kevin Mirallas is even more pleasing. It is now time to get really excited about the end of the season with that result."
The win moves the Blues up to fifth in the Premier League.
