The Foxes sit seventh in the Championship table, just a point behind Bolton after a four-game unbeaten run.
Wood's nine-game goalless spell coincided with the promotion contenders falling out of the top six, but after finding the net in his last two outings, Wood is now in confident mood and fully behind his boss.
Wood said: "He's a great manager.
"He does the business. We just need to make sure we do the business."
"He gets his teams set up right and gets everything prepared well. We just have to go out there and execute it because Nigel gives us all the tools to do it."
