Mikel Arteta hailed Arsenal fans after the 4-1 victory over Rapid Vienna in the Europa League.
A crowd of 2,000 were allowed into the Emirates Stadium – the first time supporters have been able to attend a game there since March.
Speaking at his post-match press conference, Gunners boss Arteta said: “It was very special. I was delighted to have them back and they made a huge contribution.
“They were really supportive of the team – very encouraging of the team. It did made a huge difference.
“There was only 2,000 but those 2,000 were really positive towards the team and that energy, in some difficult moments, it is appreciated and of course I appreciate a lot the support.”
Arteta also revealed that Thomas Partey is set to return to training on Friday following his recent injury.
Arsenal are hoping Partey will be able to return to action in this Sunday’s north London derby against rivals Tottenham.
“He’s training tomorrow with us and let’s see how it goes in the next couple of days,” Arteta said.
Meanwhile, Tottenham boss Jose Mourinho has said he expects Harry Kane, who has also been out injured, to be fit to play this weekend.
