KENNY Jackett believes Millwall's trip to Upton Park will serve as the perfect opportunity to make amends for their Watford horror show.
The Lions boss was highly critical of his side's midweek defeat to the Hornets and is demanding an immediate response against rivals West Ham.
"This is a massive game for us," Jackett told the club’s official website.
"Looking at our league position and the fact that we lost on Tuesday night, Saturday can’t come quickly enough. We have to play with hunger, desire, and attitude and we really have to focus on this game.
"We are fourth-bottom in the league and we want to start turning some performances into results.
"On Tuesday, we had a lot of the ball, didn’t do much with it and we defended poorly as a team – we have to put that right.
"We have to show an appetite and a hunger to compete and to win games. Our performance has to be better than it was on Tuesday."
Jackett could reshuffle his pack for Saturday's visit to east London, with new signing Andy Keogh tipped to make his debut following his deadline-day move from Wolves.
“We have opportunities to change and I’m sure a few changes will be made but we will see," the Lions boss said.
“Both sides are looking at their own league position for different reasons and wanting to have a good finish to their season.
"In my view, it's good to be playing in these sorts of games. It is a big opportunity for us on Saturday to bounce back from Tuesday and that’s the biggest thing."
