The Gunners were beaten by Francesco Guidolin Swansea City side on Wednesday as they missed the chance to close the gap on Tottenham and Leicester at the top of the table
Arsenal manager Arsene Wenger has conceded that he is worried about the Gunners' recent run of poor results.
Defeat to Swansea City on Wednesday means the north Londoners have now lost their last three matches in all competitions, with their last win having come against Leicester City on February 14.
And the Frenchman has insisted that he is concerned by the lack of wins, calling for his side to go back to basics as they look to reignite their title charge when they face Tottenham on Saturday.

He told reporters: "I think it's [the loss to Swansea] a very unlucky defeat because we created many chances. We were unlucky with our finishing, they had two shots on target and two goals all game. It's a very disappointing result and the players are very down.
"We focus on our job and come back reminding ourselves that we have some quality as well. We have another big game in three days.
"At the moment I'm more worried about our results. We've just lost three games and that's always a very difficult moment for the team. We have to come back to what we do well and do the basics."
