Wenger was pleased with the final result for his side, who have now won six of their last eight league games and also won 2-0 away over Bayern Munich in the Champions League, although still bowing out of Europe.
"I enjoyed our technical side, our creative side, our spirit and how disciplined and focused we were," said Wenger.
"The regret you have is that there were more goals in this game than the number of goals we scored.
"Overall, it's a good basis to finish the season well. Let's just keep that spirit, that attitude and play the football we want to play."
Wenger called for his side to keep their performances high over the run-in, with little margin for error if they are to gatecrash the top four once again.
"What we do is we look at the table and we are still behind Chelsea and Tottenham. We are not in a calculation mode," he said. "We can just win our next game and continue to do what we do at the moment.
"We are on a run so let's take care of the quality of our game and that run. After, we'll see where we stand.
"It (Champions League qualification) will be less predictable than it was predicted. We have a word to say in that and we want to give our best to do it."
