The Gunnners' only signing so far this season has been Yaya Sanogo on a free transfer, despite high-profile pursuits of strikers Gonzalo Higuain and Luis Suarez.

“The club is very ambitious for this year,” Arteta told Standard Sport. “Everyone in the club is happy — nobody wants to leave.
“We think we can win the title this season. If we don’t believe that, we won’t do it. I think we have got the ability to do it but we have to find the consistency through the year to earn the chance to get to April in contention and give it a go.
“We saw a few players released with the intention of bringing some new players in and I think that’s what we are trying to do to give us a better chance of winning the title.
“If someone can bring the gap much closer with the top teams, he will be more than welcome. Whether that is a big name or a smaller name who surprises us, I don’t mind, but I think we will sign someone."
The 31-year-old knows being crowned as champions next year will be difficult but is confident the club can be successful.
“I came to Arsenal to win things,” Arteta added. “I am desperate and everyone feels the same. We really want to win but we need to be realistic.
“Sometimes it comes down to small details and there can only be one winner. There are going to be four or five top teams very frustrated at the end of May next season. That’s a fact.
“When you have new faces and there is new competition, it is like fresh air around the team. And for the fans as well. They have been waiting for something big to happen. You talk to people and you can tell they are waiting for something big.”
