Henning has called on Rovers to do more defensively.
As the Rovers boss prepares his squad for Saturday's match against Brighton & Hove Albion at Ewood Park, he knows that the side's defensive frailties have proven costly in recent weeks.
"We would like to defend better, especially in the last two games," admitted Berg.
"We have to defend better in our own box, people are getting free headers and it is not nice to see.
"We have to get closer, we have to compete a lot better in those areas there is no doubt about that. It is certainly one of the areas that we are looking to improve.
"We need to read the situations, we have to concentrate, we have to focus, we have to make sure that when you are marking your man you stay with them all the way through and don't get affected by anything else."
Tickets for the match against Brighton are on open sale right up until kick-off. Priced from £15 for Adults, from £10 Seniors and from £5 Juniors.
