Emile Smith Rowe scored his first Premier League goal against West Brom on Sunday - but then had to come off with an injury.
So what's the latest on the 20-year-old's fitness? This is what Mikel Arteta told the media after the game:
on Emile Smith Rowe limping off...
I don't know, he felt something in his hamstring so we took him off.
on whether he could be out for a while...
I don't know. Sometimes he cramps and that's something that's been happening for a while because he's still adapting to the league, to the amount of games every three days.
