"I can only apologise for the display,” Upson told the official site. “Again, it was a fantastic effort from the supporters who came to watch and we didn't do them justice and that's a shame. We need to improve and keep them coming away from home.
"They've been great all season and we will be back on it in the next game."
"It's very difficult to sum it up after such a heavy defeat. We're obviously very disappointed and need to re-group and get ourselves together after a good run.
"I think we have put a lot of our efforts into our last four games and had some good results so perhaps this was one step too far for us because we were really poor.
"You need to look at it, pick pieces out of it and scrap it. That's the best way to move forward. You can't dwell on it or over-analyse it so we'll do that and get back to what I would call normal.
"It was just a poor performance - a poor individual performance and a poor collective performance and just a poor performance from everybody associated with the team. We just have to move on."
