Speaking to Arsenal magazine he said: "We still have matches left to fix the situation and to try to meet our objectives.
"It is logical that people talk because the situation has not been as it should be, but the players and club in general have to ensure that doesn't affect us.
"We have to use our energy for the matches. If you are thinking of what people are saying, you are wasting that energy. You have to concentrate on the next match.
"Every fixture now is a final we have to win. That has to be our mentality. I am sure we will put it right."
