West Ham are unbeaten in their last three league outings, having collected five points. Asked if it was too soon to describe the visit of Wolves as a must-win match, Parker said: "No, I don't think so. I think that's exactly what it is really. There's no hiding the fact we go into the Wolves game and we've got to look at it like we've got to win. They're down there with us and, if we're going to get out of it, we're going to have to beat the teams around us. Certainly, Wolves are a team we need to and try to get three points from. It's always good when you're picking up points and winning games and nicking points here and there.
"But the Premier League is the Premier League. Like we've seen all year, it seems that anyone on their day seem to be able to beat any team. It's going to be a difficult game but one we look forward to and hopefully we can pick up three points.
"I said it a couple of weeks ago: every single week and every single game is going to be crucial for us this season. That's the way it's going to be – every single game, no matter what it is, will be a game that we need to win."
Parker said he is pleased with the side's recent form that has featured the 3-1 victory at Fulham on Boxing Day and Tuesday's 1-1 home draw with Everton. "I think we obviously came into the Christmas period with winnable games. We're undefeated, four points, going into the Wolves game. Hopefully, we can go and pick up three points on Saturday and that leaves us with seven. So that'll be a good Christmas for us," the midfielder said, adding that performances have improved. "We went away to Blackburn and got a result [1-1], we obviously went to Fulham and scored three goals. Everton were much fresher than us. We looked solid and we picked up a result, which was very pleasing."
The 30-year-old, though, denied the team's run has eased the pressure. "I don't know about that. It's just such a tough league. Everyone's picking up points," he said. "We just need to stay with it and pick up some results, which I think we can definitely, definitely do."
Parker also called for the club to add to the squad during the January transfer window. "Hopefully, we can bring some players in, strengthen the squad. That would be very good," he added.
