Henry held a motivational pep talk with Howe's players while on a recent trip to the south coast on behalf of the French Football Federation.
Bournemouth boss Howe, whose team take on Henry's old club tomorrow, said: “We got Thierry in to talk to the players as we do from time to time with various people, not just footballers.
“Thierry was excellent, he spoke at length to the players about his career and how he was so successful. It was a really beneficial talk.
“It was a combination of a lot of things, definitely the mental side, his mental strength and his desire to be the best.
“There were a lot of things in there and if it is just one thing a player finds inspiring then it is beneficial. It was interesting to see how the players reacted to what he said and hopefully they took something away, not just for now but for the future."
