Mikel Arteta has hinted that Gabriel Jesus, who is out with a hamstring injury, may not be ready to return right after the international break.
The Brazilian has had a torrid time with injury, having undergone two knee surgeries within two weeks.
'I cannot guarantee that we are trying to get that recovery as quick as possible,' he said.
'I said that it will be weeks, but very difficult to put a time frame still, right now.'
Arteta has described St James' Park as one of the 'toughest places to go' as his Arsenal side prepare for a hostile battle at Newcastle on Saturday.
