The former Scotland international is keen to see a positive reaction from his players when they welcome Cumbrian outfit Whitehaven to the capital on Sunday.
“I was very disappointed, mainly due to the fact that we didn’t compete and were out-enthused,” he said.
“As a team this year, we’ve competed in every game, have been enthusiastic in our approach and certainly been defensively resilient and had some steel about us.
“Probably for the first time this season we were flat, and the players know that, they’re as disappointed as I was at the end of the game.
“They got themselves together and had a chat and it’s just been about their actions this week and responding in the right way.
“We’ve been here before where we’ve lost a game and bounced back the following week and got a result. That’s what the focus is this week.
“They’ve ripped in and are building up for an improved performance against Whitehaven at home. They are a dangerous animal because they’re probably a little bit desperate at this stage of the season.
“They need to get some points and they’ll be targeting this game. We’ve got to make sure we don’t disrespect what they’re about and ensure we go through the processes we need to go through and make sure we respond with the right attitude and in the fashion we know we are capable of.”
Whitehaven also lost last week, 36-16 at home to Dewsbury. Coach James Coyle, like Henderson, wants to see his team raise their intensity and improve on last week.
“We were pretty confident going into the weekend and thought we could get something out of the game but we were really flat,” he said.
“We didn’t play at the intensity that we normally do, it was a poor performance; they did a good job on us.
“London are in the same situation as us in looking to bounce back after a defeat.
