Arteta on Arsenal transfer demands: 'Fans must stick by the players we have'
The Gunners suffered a blow this weekend, losing 2-0 to Liverpool in the FA Cup third round at home.
The result means Arsenal are out of yet another cup, while they are also adrift of the Reds in the Premier League.
On calls to sign a striker, Arteta told reporters: "What I beg from the supporters is that they are behind the team like they have been in difficult moments.
"Stick behind the ones that we have. They are incredibly good. If not then they don't do what they've done today and in Anfield.
"Stick by them. That's exactly what they need. Then they feel important and supported. With their attitude they don't deserve anything different. That's my opinion."
He added on his players missing chances and possibly having a mental block as a result: "Probably it has. Especially after today, more than it was against Fulham or West Ham before that.
"That's why I think we need to reset. This break is good. It comes in a good time.
"We're going to as well feel how we feel and how I feel about them in difficult moments. Hopefully I can see that from other people too. When things are going well they jump on the train. Now things are difficult, let's see where they stand."
