Upson is urging the club not to sell key players in the upcoming transfer market.
“In the current climate there have not been any assurances and I would not expect any, but If I am to stay at West Ham and we sell key players in January, then that would really frustrate me,” Upson said.
“I signed for the club because of the vision they had and if players went now, that would really disappoint me.
“We are not going to get carried away on the back of three clean sheets but, hopefully, we can build on this because this is a good club.”
