Armand Traore insists Arsenal must underline their title ambitions by beating Chelsea at the weekend.
The Gunners are eight points behind table-topping Chelsea ahead of Sunday's clash at the Emirates Stadium.
And Traore told the Evening Standard: 'We will be closer to them if we get three points. There is a gap now and three points would be good.'
Manager Arsene Wenger would prefer Traore to concentrate on Tuesday's Champions League game with Standard Liege.
Arsenal have all but qualified for the knock-out stages and even a below-strength line-up should be capable of overcoming the Belgians and claiming top spot in their group.
A win would be the perfect response to Saturday's defeat at Sunderland and Wenger said: 'It's a big setback because we know that this was a very important game that we couldn't afford to lose.'
It was only the Gunners' third Premier League defeat after losing to Manchester United and City.
Wenger added: 'We were much better at City and United and were not good enough.'
