The American skipper has not been a permanent fixture in the City line-up since his summer move from Sunderland, but he understands that he is not alone.
"There are a group of us, sometimes we are in and sometimes we are out, and it's tough," said Reyna. "But we have to do a job when we are called upon, and it's going to be like that for the rest of the season."
He added: "I think places are still up in the air here and you can sense players want to take their chance. That is the positive of having a big squad."
However, Reyna had 6 weeks on the sidelines until being given another go against Leeds, which would have caused problems if that spell had continued.
He said: "I have not spoken to Kevin Keegan about my position. I have not knocked on his door. I think all you can do is try and convince him on the training pitch.
"Some players feel the need to talk and the manager has always said that if anyone needs to chat to him that's fine.
"If I hadn't played for two months then it might be different, but I don't see there is a reason for me to go and bang the door down."
But the former Rangers man was happy to be given a run out and was pleased with his and the team's performance.
"We played well over the 90 minutes and we created really good chances and played some good football," said Reyna.
"They came here to try to get a point and once they got in front they dropped even more men back. It was very similar to the pattern of an international game. I thought Leeds would come and have a go at us, expecting us to be edgy after some poor results, but they didn't.
"If we keep playing like last night then we should turn the corner."
