Wenger is set to have plenty of cash available to improve the Gunners' squad when the transfer window re-opens and the Frenchman wants his players to show him there is no need to bring in reinforcements for their position.
"We have to analyse. What will decide our attitude, my attitude, is how we do now until the end of the season," said Wenger.
"We have had some blips that were not expected, Blackburn and Bradford, but overall I must say the attitude of the team has been great and when everyone is here (fit), then we have a strong team.
"What is important is to analyse where we can improve at the end of the season."
Wenger does however believe his current squad deserve credit for the way they have hauled themselves back into UEFA Champions League contention with a run of five wins in the last seven league games.
"They have gone through difficult times and have responded well," he said.
"They have shown mental strength as we lost against Blackburn, Bayern and then Tottenham, so as well they could be scared that the group implodes.
"We have shown a strong response against Bayern (away) and also Swansea, so that shows that this group is mentally strong."
