Arsenal manager Arsene Wenger has admitted his side cannot afford to drop any points if they are to qualify for the Champions League after the Gunners narrowly triumphed over QPR.
The relegated side were unable to find a response after Theo Walcott opened the scoring within 20 seconds as Arsenal secured a win that put them 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 they were just as good as their 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."
