Upson also insists the whole squad are united behind under-fire manager Gianfranco Zola.
“I think we can stay up, I think we are good enough,” he said.
“We are aware of the situation and the manager’s feelings and commitment. The manager deals with it with the players to their faces.
“Whatever else is said and done, we know the truth and we are together as a group.
“We are totally understanding and clear of the picture of what is going on. We are putting everything we can together.”
“We had a really good week, we got together as a group and worked hard on the training pitch on things we had been doing poorly over the last few games,” Upson added.
“It is something to build on but there is plenty of work left to do.
“There are not a lot of hours of football but we are in the mix and it is up to us to drag ourselves out of it.
“We had a really good week, we got together as a group and worked hard on the training pitch on things we had been doing poorly over the last few games.
“We need to get together again this week, have a good strategy for the weekend and commit to it.”
