Gardner has suffered one relegation during his career with Birmingham City.
The midfielder said: "We are all as one. We are all together. Regardless of what the press, pundits say, we are together and we will get through this.
"It's no good thinking we are going down, we are doing this. I was in the Birmingham City team that went down. We had a lot of fight but we never had the quality we have here. If we have that fight we need, that we dig deep, we will be fine. We need to do that.
"I have been through it. It's not nice because, people lose their jobs. There's like a domino effect. A lot of people from outside the club won't see it. We will make sure we can turn it around."
