He's got another MRI this afternoon because he had quite a lot of fluid in the area so it was difficult to understand the extent of the injury, Arteta said.
We need a few more scans and opinions from the specialists, Arteta said. When a player has to walk off the pitch, he is struggling to walk without any pain, and is restricted to movement; it is not a good sign.
I do have to be careful, yeah, said Arteta.
