They have lost four of their last six away games, and Nasri says that record has to be improved if they are to keep the pressure on Arsenal before their showdown in a fortnight's time.
"We have a tough week, we are playing two games away from home.
"The most important thing now is to recover from this game and be ready against West Brom because we have to improve our form away from home.
"We have to mind the gap with Arsenal before we play them here and we have two games away from home.
"We have to show the same mentality and the same desire we have at home. We are a good team but now we have to show it away from home."
