Arteta told reporters: “I'm very happy with the players that we have. When you look at the amount of goals that we have scored as well, it is more than enough to win the Premier League. But the reality is somebody is doing more. And that is the reality of life so we have to do better.
"Signing somebody is not enough, that is for sure. That signing has to score then how many goals? A lot of things have to happen. That (January) market is much more limited than in the one summer, but I don't know.
"If something extraordinary is in the market that we can afford and we think will have a real impact on the team we have to be open for that possibility always. At the moment, the focus is on what we have.”
He added: "When you are in that moment you want to continue to play. Gabriel has had a massive step up in load in recent weeks. We are going to have to try and manage the players."
