With 17-goal Olivier Giroud serving the second part of a three-match suspension, Wenger must again decide who should lead the Gunners attack when they travel to relegated QPR on Saturday.
Wenger opted for Podolski ahead of leading scorer Theo Walcott against Manchester United last weekend, when it was the England forward who put Arsenal into an early lead before the Barclays Premier League champions fought back to draw.
Podolski, signed from Cologne in the summer, has been deployed down the left for most of the season or as an impact player from the bench, but has shown glimpses of his ability in and around the opposition box with his 14 goals.
Wenger believes there is plenty more to come from the 27-year-old.
"Podolski was a little bit rusty (against United) because he had not played a lot, but I believe it is his best position maybe because on the flanks he needs to work so hard and he is more a finisher than anyone else in the team," Wenger said.
"It is a good opportunity for him to show that he has a future in this position and that he can finish, but first I must decide to play him there.
"Overall if you look at his numbers he had quite a good season, but not through the middle, on the flanks, but I am convinced through the middle he can have a great goalscoring record."
Arsenal head to Loftus Road on the back of a seven-match unbeaten league run which has moved them into fourth place - one point behind Chelsea and two ahead of Tottenham, albeit having played a match more.
Chelsea, who on Thursday night reached the Europa League final, head to Manchester United on Sunday, before then hosting Spurs next Wednesday.
Wenger feels if his team go on to take maximum points from their own remaining fixtures - which are also at home to FA Cup finalists Wigan and then at struggling Newcastle on the final day - they should secure another campaign of Champions League football.
"What is important for us is that we finish well and then think that we have done the maximum that we could," said Wenger.
"Does it go for us or not? I don't know.
"It depends a little bit on the other results. What is important is that we win our games."
Last season, Arsenal finished third with 70 points, just one ahead of Tottenham, who eventually missed out on the Champions League when Chelsea went on to win the final against Bayern Munich.
Wenger said: "If we win all our games we will have 73 points and if we are not in the Champions League with 73 points, or fourth with 73 points, which is unlikely, at least you have done the job.
"But there is one chance out of 100 or I don't know how many, that even that will not be enough."
Wenger believes his side deserve some credit for the way they have recovered from the sale of captain Robin van Persie to United last summer.
He added: "We lost a great player, I don't want to deny that, and we didn't want to sell him to Man United, but we started in a very negative environment.
"I think the team has good focus, good basic quality, and if we finish at that level it will be all right, but it is not done."
Wenger has again moved to distance himself from a summer move to big-spending Paris St Germain, insisting he will honour his contract which still has a season to run and hinting he would like to stay on past 2014 to help the latest generation finally end their trophy drought.
"We have good stability, on both flanks, the full-backs, we are quite strong and defensively we have stabilised the team, we have to add, I agree, but the basis is there," Wenger said.
"If you look at the passing statistics in the final third we are ranked one, in the opponent's half we are ranked one.
"Yes we have to be more efficient, but there is a good technical basis there."
