The Gunners boss highlighted the unpredictability of the top-four battle as Arsenal pushed two points clear of Tottenham and Chelsea with a narrow win over already-relegated QPR
The relegated side was unable to find a response after Theo Walcott opened the scoring within 20 seconds as Arsenal secured a win that put it two points ahead of rivals Chelsea and Tottenham, before the latter two meet on Wednesday.
However, Wenger is wary of the unpredictability of the Premier League run-in with qualification to the Champions League - and the subsequent financial rewards - in the balance.
"We're on a very strong run and want that to carry on until the end of the season. You can only win your own games and watch what happens elsewhere," he told ESPN. "Chelsea play Tottenham on Wednesday and they're at Manchester United [on Sunday]. Football is unpredictable but for three months we've been in a position where we cannot drop points."
QPR boss Harry Redknapp, meanwhile, lauded his side's "first-class" efforts, claiming that it was just as good as its opposition in spite of the result.
"We showed fantastic spirit, we were every bit as good as them today. We could have got a result today, the spirit was first class," he told ESPN. "What more could we have done? We conceded a goal and we could easily have dropped our heads, we kept going, we worked their keeper.
"I thought we were excellent. It's easy to jump on the bandwagon to say there was a lack of spirit, [but] there wasn’t today."
