The Red Devils finally brought their three-game losing run in the Premier League to an end thanks to a close-fought stalemate with the defending champions.
Van Gaal’s side produced one of their most-energetic performances of the season to dispel speculation that the Dutchman had lost the dressing room in recent weeks.
While Henry was impressed with United’s performance in Monday night’s clash, the Arsenal legend pointed out that Chelsea played into the Red Devils’s hands.
Henry told Sky Sports: “It’s another game without winning, that’s eight now, and another 0-0 draw at Old Trafford.
“I don’t think I would have ever said that in my lifetime. But there was something about them on Monday that maybe sparked something, a new beginning maybe.
“But how much was that down to Chelsea not playing well? They allowed United to be on the ball, there wasn’t much pressure, they didn’t have a striker, with [Eden] Hazard playing as a false No 9.
“Van Gaal said that he has the board with him. I think they better start to win football games because he will have to deal with a tricky situation, and at one time the board may find themselves dealing with the same situation the Chelsea board had not that long ago.”
United are in sixth place and nine points behind Premier League leaders Arsenal following their goalless draw with Chelsea at Old Trafford.
The Red Devils host Welsh outfit Swansea City at the Theatre of Dreams as Van Gaal’s side aim to win their first game in eight attempts in all competitions.
