Laurent Koscielny made his comeback to first team football on Thursday night in Arsenal's 1-0 win against Qarabag.
The Frenchman had been out of action since rupturing his achilles against Atletico Madrid in May.
And Koscielny revealed after the game that he was 'very happy' to be back playing.
"It was very important for me today," the French centre-back said, per the BBC.
"It is difficult being out injured. It was the first big injury of my career and I had to take a long time out, but you learn a lot about yourself and I am very happy.
"I am focused mentally, and I can smile and enjoy the rest of the season."
There is a feel good factor at the club, with Arsenal currently on a 22 game unbeaten run.
It's evident that this Arsenal team have an abundance of team spirit and camaraderie, and that was shown after Koscielny was subbed off on Thursday night.
While making his way to the bench, Matteo Guendouzi and Alexandre Lacazette had a quite lovely welcome for their countryman.
Both stood up and gave him a warm applause, before Guendouzi assisted him with putting on his coat.
Lacazette even attempted to put his hat on for him, although Koscielny declined.

That is heartwarming. The 33-year-old looked rather embarrassed throughout but he would no doubt have appreciated the welcome from his teammates.
The video has been doing the rounds on Twitter, with many Arsenal fans expressing their joy at the moment.
Despite Koscielny being able to complete 72 minutes on Thursday, Unai Emery admitted he did not know whether he would be available for Sunday's match against Southampton.
"Today is another step for [Koscielny]," Emery said, per Goal.
""We need to [find out] tomorrow and Saturday how he is going to feel after this match to see if he can help us on the pitch on Sunday.
"It is good he has recovered and in a good time. Every supporter and player from Arsenal is happy.
"He can take confidence again, take rhythm and then we are going to continue our process. Maybe [he can play] Sunday, but I want to wait to see how he will feel."
