"It is still very positive; it is a long season and there are a lot of games to go, so there is no need to be down in the dumps," he stresses.
West Ham are hoping to avenge the recent 1-0 defeat at Loftus Road and he adds:
"We have a score to settle and a point to prove so it is a very important game - we are looking forward to the game very much."
He acknowledges the difference between the displays at Upton Park and on the road, though, and adds:
"The home form has been good but we have to take that into the away games as well."
Nigel is now the last of the 'Three Musketeers' from Wimbledon - the other two, signed around the same time as him, having gone.
Adam Nowland has moved on to Nottingham Forest for £250,000, and Jobi McAnuff, who scored against West Ham on Tuesday for Cardiff, moved on earlier in the season.
"It was inevitable Jobi would have a good game against us because he will have felt he had a point to prove," smiles Nigel.
As for the departure of Adam, who started against Chelsea last week, Nigel adds:
"That is the game we play; I will stay in contact with him and I know he will do very well.
"He is a great player with lost of ability and I am sure he has a bright future ahead of him."
Nigel is included in the squad to face QPR after missing the trip to Wales with a knee injury, and he says:
"I want to play as many games as possible but of course I was unable to play on Tuesday.
"I have had a problem with my knee for a while and I am just trying to look after it now and see what happens - it has been an ongoing thing.
"We will have to wait and see whether I will be able to play - hopefully I will."
