Mulumbu is also eager for his team-mates to put right Octoberâ€™s 2-1 defeat by City in which the Baggies were heading for victory with ten minutes to go only to be undone by Edin Dzekoâ€™s late double.
â€śIt's always exciting to play against a big side,â€ť he told the WBA website. â€śWe don't even need the gaffer to speak a lot when you play against big sides.
â€śWe will be ready to do something. We don't need to be scared about City or about United. Weâ€™ve shown some good things against big teams. I'm really confident and I hope we're going to win.
â€śI'm looking forward to playing against this team and that's a big test for West Brom to see where we are.â€ť
