He was frustrated by the stalemate against the Saddlers at the weekend, and admits:
"There was plenty of effort and commitment, and we had good possession at times, but I think in the first half we didn't play at a high enough tempo which meant we didn't create as much as we would have liked, and it allowed Walsall to set their stall out a little bit.
"Although we did up it a bit in the second half it was probably too late by then because we didn't get the start we would have wanted.
"We have another big game on Tuesday, another one we have got to win, and we must keep going, there is no doubt about it.
"It is going to be every bit as tough as Saturday, and you have to give Walsall a bit of credit because they made it difficult for us to create chances, although we did eventually get a few.
"Wimbledon will probably do the same thing as well, they will come here fighting for their lives - although we are as well.
"Games are not always pretty but we must deal with that.
"The fans will be important again and we need them behind us as they were for most of the game on Saturday - we need everyone sticking together at the club."
Matthew Etherington returns from a one match ban and Christian says:
"Mattie is a great winger and he gives us such an outlet on that left hand side; the balance was probably affected by the fact that he wasn't there on Saturday so I am looking forward to him coming back - and he will be fresh."
Despite the 10 point gap to second placed West Brom - and indeed leaders Norwich - Christian says:
"We still feel we can do it, there is no doubt about that, and there is no way we are giving up - no chance.
"There are a lot of games to go and a huge number of points to play for.
"We can't lose faith and there is more to come from a young side."
