Arsenal kicked off their Premier League campaign at home to Nottingham Forest in Saturday’s early Premier League match.
The Gunners ran out 2-1 winners on the day thanks to goals from Eddie Nketiah and Bukayo Saka.
However, it was not all positive for Arsenal on Saturday as new signing Jurrien Timber suffered an injury.
Timber’s afternoon lasted only 50 minutes amid concerned faces at the Emirates Stadium as he limped off with an apparent knee or calf issue, replaced by Takehiro Tomiyasu.
On the injury, Mikel Arteta said: “The doctors looked at him and they were happy for him to continue, he was as well. Straight away in the first action of the second half he made a movement and it was a bit funny.
“We took him out straight after and now we have to assess him and see what he has.”
It was somewhat surprising to see Tomiyasu come on for Timber over Gabriel, leading to speculation the South American was also injured.
But when quizzed on if leaving the Brazilian - a regular starter last season - on the bench was merely a tactical decision, Arteta said: “Yeah, we expected a game that actually happened and we needed somebody else in midfield to do what we did best, to have more fluidity and occupy certain spaces in relation to how they’re defending. It worked really well.”
