The 24-year-old appears to have established himself as Solskjaer's No.1 at the moment following a number of impressive displays.
But just as the United boss was praising De Gea in an interview with Sky-Sports, the cameras panned to him and captured the Spaniard spilling two balls that were fired into him.
Henderson, to his left, caught both of them and made former Atletico Madrid man De Gea look a bit of a fool in the process.
"Dean [Henderson] has had good momentum, he's played really well so we carried on with him today," Solskjaer said to Geoff Shreeves pre-match.
"David [De Gea] played well in Granada, kept a clean sheet, but he played - travel and everything. Dean had more of a rest so he's in goal today."
Solskjaer has said that he feels he has "two number ones" to choose from but his former teammate and skipper Roy Keane is not buying it.
The Irishman believes Henderson is firmly first choice in Solskjaer's eyes and now has the edge over De Gea, United's No.1 shot-stopper since 2011.
"I wouldn't agree with Ole, I think he sees Dean Henderson as his number one now," Keane told Sky Sports.
"He's given him a run of games - okay, he played De Gea in the week, which was a comfortable game. He's given Dean his trust in him now to play in the big games.
"He's certainly going to get until the end of the season, unless he has a complete disaster, so I think De Gea is under huge pressure now to try and get his position back in the team."
