Arteta said: “Hopefully we can deal without Tim but it is a massive, massive loss.
“He is a really important player and we need him. It’s not just about his goals. He’s got presence and he’s a great character in the dressing room. He has been really good for us.
“Now he is out, we have got to look forward. Maybe Ossie will come in. Maybe it could be Victor (Anichebe) or Vaughany. Everyone will have a role to play from this point and it is crucial that we all do our best.
“Can I get 10 goals? I will try my best. I want to score as many as I can to help the team. The gaffer keeps asking me to improve the number of goals I score and I want to become a better player. If I can score a lot of goals, that will help the team.”
The Spaniard added: “Being in sixth place is massive and it helps us after what happened to Tim. In terms of confidence, it has given us a really big lift, as it was a game that we looked like losing.”
