Reports broke this week which claimed the German had rejected a new contract offer because he wants to leave on a free transfer next summer.
But when asked about his contract situation, Mustafi said that although talks were not underway, he would like to remain at the Emirates.
"At the end of the day, it was important for me in the last three months to come back after the injury and to be ready to play and to help my team.
"When you hopefully get a few games, you can maybe look at the future but at the moment for me it has been difficult because in the last months, I haven't really been thinking about the end of my contract or what's going on with the future because all I wanted was to be back as quick as possible.
"At the moment I was just happy to come back from injury, it was three long months - I was happy just to come back and be able to play again.
"We haven't been talking about anything so there isn't anything I can tell you guys.
"Now for me it is important to just get a few games and get into the match rhythm and then see how it goes."
