Theo Walcott has struggled to watch Arsenal flying in the Premier League from the sidelines as he continued to recover from an abdominal injury.
Walcott had been out of action since mid-September but the England international made a comeback in the Gunners' 2-0 win over Southampton at the weekend.
He was able to get around 20 minutes of game time and as he works to get back to full fitness Walcott admitts it has been difficult not having a part in Arsenal getting hold of top spot in the table and asserting themselves as the side to beat in the Premier League.
He told reporters: "It has been longer than I thought, but it is so good to be back out on the pitch with the guys and playing in such a fantastic team.
"Seeing the way we play football has been fairly pleasant to watch (from the sidelines), but any player who is injured wants to go out there and perform.
"It is frustrating at times, but you have just got to think about getting back fit as soon as you can, and I am happy to be back now."
Walcott will be hoping to get even more game time when Arsenal take on Marseille this Tuesday and as the side look to take hold of top spot in the Champions League Group F his return will be welcomed by Arsene Wenger, who has had to rely heavily on Olivier Giroud to head the attack for the side this season.
Walcott's return coincides with the manager confirming that Lukas Podolski is on his way back into the first team as well, providing Wenger with a much more stable front-line.
