Speaking to reporters, Arteta said: "We had a clear intention which is always there is a window open to explore the opportunities to improve our squad with players that can impact it. We haven’t achieved it so we are disappointed in that sense but as well we are very aware that we only want to bring certain kinds of players and we have to be very disciplined with that and I think we will.
"It’s not a gamble, it’s reality. I think we have to face the reality as well that we have. So we’re going to have to evolve there as well and have more and have more players from the academy and the ones that are here to be fitted longer."
He added: "That’s a job that is permanent and it keeps evolving and we need to be on our toes. We’re going to have to be very flexible in the front line and now the ones that we have and are fit, make sure that they stay fit and they keep contributing."
