David Moyes was proud of his Sunderland players and dismissed Wenger's comments made on Monday that some Premier League teams had "released their focus" once they had nothing to fight for.
"I felt he had something still left", Wenger said.
While Manchester City need just a point to guarantee finishing above Arsenal, Arsene Wenger's Gunners could potentially take advantage of any Liverpool jitters.
"We had 36 shots on goal, the highest ever in the Premier League and their keeper saved 11 of them, he has done extremely well".
Alexis Sanchez's brace means Arsenal could yet secure a top-four finish by beating Everton at home on Sunday.
Two goals from Alexis Sanchez moved Arsene Wenger's side to within a point of Liverpool in the race for the Uefa Champions League places, with Everton set to visit the Emirates stadium this weekend. If Manchester City, Liverpool and Arsenal win their respective games, Man City will finish 3rd and Liverpool will finish 4th.
Wenger played down the fans" no-show, saying: "No, I wasn't surprised.
Relegated Sunderland frustrated Arsenal until Sanchez popped up to score twice from close range in the final 18 minutes, taking his tally for the league campaign to 23 goals.
The Arsenal manager was unsure of starting Sanchez due to a knock he was carrying, but forty minutes prior to kick off, Wenger made his decision and threw Sanchez into the starting line-up.
"Once he is on the pitch and gets the ball, he always becomes a devil and forgets the pain".
Thousands of fans stayed away, whether out of apathy or in response to calls from some fans to boycott the fixture as a show of dissatisfaction, with Emirates Stadium looking no more than three quarters full. It's Tuesday night against Sunderland, who everyone expects us to beat.
The Scot added: "We had a very good goalkeeper tonight, who was outstanding".
Moyes said that British players had too much pride to ever give anything less than 100 per cent, a common theme of his this season. "You play because you want to win the game and because you enjoy to play".
